The International Brotherhood of Police Officers (IBPO) is a police labor union, a member organization of the National Association of Government Employees, which is itself affiliated with the Service Employees International Union.^[1] IBPO's sister organization is the International Brotherhood of Correctional Officers (IBCO).

Counting only officers, the union has over 15,000 members.^[2]

IBPO's membership is geographically diverse, representing police officers in Boise, Idaho,^[3] the members of the Coastal Florida Police Benevolent Association & Public Employees Association,^[4] members of the Atlanta Police Department in its southeast regional division, and members of local 105 in Cranston, Rhode Island, where the union was founded in 1964, after a dispute over a test led seven unfairly fired officers to the state legislature, then to the state supreme court, to win reinstatement.^[5]

IBPO first joined NAGE in 1970. As of 1983 it was one of four police unions aspiring to a national membership, along with the Fraternal Order of Police, the International Union of Police Associations, and the National Association of Police Organizations.^[6]
