Police badges of America’s largest departments
This editorial reference covers the badges worn by the ten largest municipal police departments in the United States. The information below is compiled from each department’s published history, public records, and museum sources. It is not a buying guide and does not offer reproductions of these badges. We describe shapes, structures, and historical context; we do not display the copyrighted images of any department’s badge. Last verified May 2026. See full methodology.
Who this reference is for
Researchers studying American law enforcement history, journalists and writers needing accurate badge descriptions, law enforcement officers curious about how their department’s badge compares to peers, museum staff and collectors documenting institutional history, and the general public interested in understanding the visual identity of major American police departments.
This is a structural and historical reference, not a buying guide. Each department’s badge is its own protected institutional symbol. We describe the badges in editorial detail without reproducing them visually, in keeping with standard reference-writing conventions used by Wikipedia, the Smithsonian, and academic publications.
Why these ten departments
The ten departments covered here are the largest municipal police departments in the United States by sworn officer count, as reported in the most recent Bureau of Justice Statistics data and current department disclosures. Together they account for over 85,000 sworn officers — roughly one in nine sworn municipal police officers nationwide.
Sheriff departments, state police, and federal agencies are not included on this page. County sheriff badges are covered separately in our sheriff badge reference. State police and federal agency badges follow different design traditions and warrant their own dedicated reference pages.
The ten departments are listed alphabetically below. Listing order does not indicate ranking or preference.

The departments in detail
Each department’s history, badge shape and structure, rank variations, and notable elements. Departments listed alphabetically.
The Boston Police Department is the oldest municipal police force in the United States, established in 1838 — predating the New York Police Department by seven years. The Boston badge is a traditional shield shape with a domed top, used by both patrol officers and command staff with rank-specific finish variations. The center of the badge displays the City of Boston seal, which incorporates a Latin motto and the city skyline. Patrol officer badges are silver-finished; command staff and detective badges are gold. The badge number panel sits at the lower portion of the shield. Boston’s badge tradition reflects its New England civic heritage, with design elements that have remained recognizably consistent across multiple 20th century redesigns.
The Chicago Police Department, founded in 1837, is the second-largest municipal police force in the United States. The Chicago badge is distinctive among major departments for its five-point star shape — a design choice more commonly associated with sheriff badges and Western law enforcement than with East Coast municipal forces. The current five-point star design was adopted in 1955, replacing an earlier six-point pie-plate style used through the early 20th century. The badge displays the City of Chicago municipal seal at the center, surrounded by the words “Chicago Police” and the officer’s badge number. Patrol officers wear silver-finished stars; supervisory and command ranks transition through silver-and-gold combinations to fully gold finishes for senior command. The star shape, unusual for an East-of-Mississippi major department, reflects Chicago’s historical position as a transitional city between Eastern and Western American policing traditions.
The Dallas Police Department was established in 1881 as the city transitioned from frontier town to major Southwestern commercial center. The Dallas badge is a five-point star, consistent with Texas state badge traditions established by the Texas Rangers and reflected across most Texas municipal departments. The Texas star shape connects Dallas visually to a broader state law-enforcement identity rather than to East Coast municipal shield conventions. The center of the badge displays the City of Dallas seal, which incorporates references to the city’s founding and its role as a regional trade hub. Patrol officers wear silver-finished stars; command staff wear gold. Dallas’s badge convention reflects the broader Texas pattern in which star-shaped badges dominate at both county and municipal levels, regardless of department size or urban character.
The Detroit Police Department was formally established in 1865, shortly after the Civil War. The Detroit badge is a shield shape with the City of Detroit seal at the center. Detroit’s badge design carries influence from the broader Michigan badge tradition pioneered by the Weyhing Brothers manufacturing firm in Detroit, which produced badges for state and municipal departments from 1903 through 1983 and shaped Michigan’s distinctive badge aesthetic. The shield is typically finished in silver for patrol officers and gold for supervisory ranks. The badge number appears in a dedicated panel at the lower portion of the shield. Detroit’s police badge has undergone refinements through the 20th and 21st centuries, but the shield shape and central seal placement have remained constant.
The Metropolitan Police Department of the District of Columbia (MPD or MPDC) was established by Congress in 1861 during the Civil War and serves the federal district. The DC Metropolitan badge is distinguished by an eagle-topped shield — the eagle elevated above the shield reflects MPD’s role as the police force of the nation’s capital and its proximity to federal authority. The shield itself bears the District of Columbia seal at the center. The eagle-topped shield design is uncommon among municipal departments and visually signals the department’s federal-district context. Patrol officers wear silver-finished badges; supervisors and command staff wear gold-finished badges with additional decorative elements indicating rank.
The Houston Police Department was established in 1841, four years after the founding of the City of Houston. The Houston badge is a five-point star, consistent with broader Texas badge tradition. The center of the badge displays the City of Houston seal, which incorporates a locomotive and plow reflecting the city’s 19th-century identity as a commercial and transportation center. The Houston badge is among the larger municipal department badges by physical dimension, reflecting the department’s substantial size and the visibility expected of officers in a major metropolitan area. Patrol officers wear silver-finished stars; command staff wear gold. Houston’s badge convention places it alongside Dallas, San Antonio, Austin, and other major Texas municipal departments in maintaining the state-wide star tradition.
The LAPD is the third-largest municipal police department in the United States and is among the most globally recognizable due to extensive film and television portrayal. The LAPD badge is a distinctive oval shield — a shape that the department adopted in 1940 and that was uncommon in badge design at the time of adoption. The badge centers on a detailed engraving of Los Angeles City Hall, surrounded by laurel leaves symbolizing honor. The border design draws from the Roman fasces, an ancient symbol of authority. Rays around the central seal represent a West Coast setting sun. The badge displays “Police Officer” (or the officer’s rank) across the upper arc and “City of Los Angeles” along the lower arc. The unique oval shape distinguishes LAPD badges immediately from the shield-and-star traditions used by most other major departments. Read the full LAPD badge history and design reference →
The Miami-Dade Police Department in its current form was established in 1957, though predecessor agencies date back further. Miami-Dade is unusual among major American police departments in serving both incorporated and unincorporated areas of a large county, functioning more like a metropolitan police service than a strictly municipal force. The Miami-Dade badge is a shield shape displaying the Miami-Dade County seal at the center. The badge design reflects the department’s combined municipal-and-county jurisdiction, with the county seal anchoring the badge rather than a strictly city-level seal as appears on most other entries here. Patrol officers wear silver-finished badges; supervisors and command staff wear gold. Miami-Dade’s badge is the most recently established design among the ten departments in this reference, reflecting the department’s mid-20th-century origins.
The NYPD is the largest municipal police department in the United States and one of the most globally recognized law enforcement agencies. The NYPD badge — universally called the “shield” within the department — is a traditional shield shape with a rounded top and pointed bottom, displaying the seal of the City of New York at its center. The current shield design dates to approximately 1902, with refinements over subsequent decades. NYPD shields are notable for varying significantly by rank, with each rank carrying a structurally distinct badge: patrol officer is a plain shield, sergeant adds an eagle top, lieutenant uses a starburst configuration, captain uses an oval with crown and leaf clusters, and command staff continue the structural progression. Detective shields use a round starburst with a panel — visually distinct from any patrol-rank badge. Patrol badges are silver-toned with blue enamel; command and detective badges shift to gold. The shield’s first use in 1845 was as a hand-stamped copper piece, the origin of the slang term “cops” (from “coppers” referring to those copper shields).

The Philadelphia Police Department was consolidated into its current form in 1854, drawing together a patchwork of earlier ward-level constabulary forces. The Philadelphia badge is a shield shape displaying the City of Philadelphia seal at the center. Philadelphia’s seal incorporates references to the city’s founding by William Penn and includes a ship and plow representing commerce and agriculture. The shield design reflects East Coast municipal badge conventions — straightforward shield shape, central city seal, finish variation by rank. Patrol officers wear silver badges; supervisors and command wear gold. Philadelphia’s badge tradition closely parallels Boston’s and New York’s in design language, all three drawing from a shared 19th-century East Coast municipal heritage that established the shield as the default American police badge shape for the region.
Patterns across the ten
What the ten departments tell us about American municipal badge tradition.
Shape divides geographically, not by size. Among these ten departments, the shield shape dominates the East Coast and Midwest (Boston, NYPD, Philadelphia, Detroit, Miami-Dade, DC) while the five-point star dominates the Southwest and Texas (Chicago, Dallas, Houston). LAPD’s oval shield is genuinely unique among major U.S. departments. Department size has no correlation with shape — NYPD’s shield and Chicago’s star are the badges of the two largest municipal departments and they look nothing alike.
Central seal is universal. All ten departments place a municipal or county seal at the visual center of the badge. The seal anchors the badge to a specific jurisdiction and prevents visual confusion with other departments using similar shapes. A shield without a city seal would not be recognizable as the badge of any specific department.
Rank is signaled through finish, not shape — with NYPD as the exception. Nine of the ten departments use the same badge shape across all ranks, varying finish (silver to gold), surface decoration, and supplementary elements (chevrons, oak leaves, stars) to indicate rank. NYPD is the lone exception, using structurally different shield variants for each rank — a sergeant shield, lieutenant shield, captain shield, and detective shield are not just refinished versions of the patrol shield but separate badge configurations.
The current designs are mostly mid-20th-century. Most of the badges worn today were designed or last substantially revised between 1940 and 1965. The LAPD’s 1940 oval and Chicago’s 1955 five-point star are documented redesigns from this period. The earlier 19th-century badge designs of these departments have been retired or kept only for ceremonial use. The mid-20th-century redesign wave reflected the professionalization of American policing and the standardization of badge manufacturing techniques.
Federal-district status changes badge design. The DC Metropolitan Police Department’s eagle-topped shield is the only badge in this group that visually signals federal-district context. The eagle, common on federal agency badges, would be unusual on a strictly municipal force; MPD’s use of it reflects the department’s unique role as the police service of the nation’s capital.
Texas convention crosses jurisdictional lines. Dallas and Houston both wear five-point stars, identical in concept (if not exact dimensions) to the badges worn by Texas Department of Public Safety, Texas Rangers, and most Texas county sheriffs. Texas badge tradition is distinctive in this regard — most other states show clearer visual separation between municipal police badges (shields) and county sheriff badges (stars). In Texas, the star spans both.
Frequently asked questions
Chicago’s five-point star is a 1955 redesign that replaced an earlier six-point “pie plate” style. Both star designs reflect Chicago’s historical position as a transitional city between Eastern (shield-using) and Western (star-using) law enforcement traditions in the 19th century. Chicago grew alongside the westward expansion of American policing and adopted the star at a point when it identified more strongly with frontier-style law enforcement than with East Coast municipal conventions. Once established, the star tradition was self-reinforcing; the 1955 redesign refined the star but did not abandon it for a shield.
The LAPD adopted the oval shield in 1940. The oval shape was deliberately chosen to distinguish Los Angeles from East Coast shield-using departments and from neighboring California sheriff departments using stars. The shape also accommodated the detailed central engraving of Los Angeles City Hall, which is the visual centerpiece of the design. The fact that no other major department has adopted the oval since LAPD established it in 1940 reflects how strongly each department’s badge identity becomes tied to its specific shape over time — copying LAPD’s oval would visually associate any other department with LAPD rather than establish its own identity.
Yes. NYPD is uncommon among American municipal departments in that each rank wears a structurally distinct shield rather than a refinished version of the patrol shield. A patrol officer’s shield, sergeant’s shield (eagle top), lieutenant’s shield (starburst), captain’s shield (oval with crown and leaf clusters), and detective’s shield (round starburst with panel) are all separately designed badges, not the same badge in different finishes. Most other major departments use one shape across all ranks and vary the finish, surface details, and rank designation. NYPD’s rank-distinct shield tradition dates to the early 20th century and is a recognized cultural feature of the department.
The widely accepted etymology traces “cops” to the copper shields worn by NYPD officers when the department was first established in 1845. Officers wearing the hand-stamped copper badges became known as “coppers,” which was eventually shortened to “cops.” Alternative theories exist — including claims that “cop” derives from “constable on patrol” or from the verb “to cop” meaning to catch — but the copper-badge origin is the most historically documented and is widely accepted by linguists and police historians.
Yes, in most cases. Police department badges are typically protected by trademark (the design as an identifier of the department) and copyright (the specific artistic rendering). The City of New York, City of Los Angeles, and most other municipalities own intellectual property rights in their police badge designs. This is why authentic badges can only be ordered by verified officers or authorized representatives of the department, and why unauthorized reproduction is illegal — both under state impersonation statutes and under intellectual property law.
