In Brazil, the Federal Constitution establishes eight law enforcement institutions - seven titulars and one auxiliar. The titular institutions are: the Federal Police, the Federal Highway Police, the Federal Railroad Police, the Federal Penal Police, the State Military Police and Fire Brigade, the State Civil Police and the State Penal Police. Of these, the first four are affiliated to federal authorities and the latter three are subordinated to state governments. These public safety institutions are part of the Executive branch of either federal or state government. Apart from these eight institutions, there are others which affiliate to municipal authorities: the Municipal Guards. According to Minister Alexandre de Moraes of the Supreme Federal Court, "...the Municipal Guards are inserted in public safety as the auxiliary and related body of public security force..." Federal law 13,022 gave them de facto and de jure police attributions.

The Department of Federal Police is a federal law enforcement agency of Brazil and one of the three national police forces. The other two are the Federal Highway Police, and the National Force. From 1944 to 1967 it was called the Federal Public Safety Department.
