The National Police Service (Bulgarian: Национална Служба Полиция), also known as the General Directorate "National Police" (Главна дирекция "Национална полиция", ГДНП) is an independent agency of the Ministry of the Interior responsible for general law enforcement in Bulgaria.

With the creation of the "Law for administration and police" in 1925 was established the "Police and State Security Directorate" .

Its duties included enforcing laws and ensuring the safety of the country. It continued to function until 1944 with the creation of the People's Militia.

The People's Militia (Bulgarian: Народна милиция) was established by the Council of Ministers with Decree No. 1 on 10 September 1944 (one day after the communist coup).

The Directorate of the People's Militia was structured into two departments: State Security and People's Militia.

On April 1, 1947, the Main Directorate of the People's Militia was established, which included the Directorate of State Security and the Directorate of the People's Militia.

The militia functioned as a basic police force, but also acted as an intelligence agency and spied on both its own and foreign citizens, secretly gathering information for the communist party.

With the democratic changes of 1991, the People's Militia was replaced by the National Police.
