The '''Security Service''' ({{langx|pl|Służba Bezpieczeństwa}}; {{IPA|pl|ˈswuʐba bɛspʲeˈt͡ʂɛɲstfa}}), in full '''Security Service of the Ministry of Internal Affairs''' and commonly known as '''SB''', was a [[secret police]] force established in the [[Polish People's Republic]] in 1956 as a successor to the [[Ministry of Public Security (Poland)|Ministry of Public Security (UB)]]. The SB was the chief foreign and domestic [[Intelligence agency|security organization]] in Poland from 1956 until the fall of communism in 1989.

The parent agency of SB, the Ministry of Internal Affairs, had been established in 1954, but the Ministry did not play a significant role until the winding-up of the Committee for Public Safety in 1956.
