Friedrich Wilhelm Ernst Busch (January 22, 1900 – June 8, 1980) was a German singer and actor.

Busch first rose to prominence as an interpreter of political songs, particularly those of Kurt Tucholsky, in the Berlin Kabarett scene of the 1920s. He starred in the original 1928 production of Bertolt Brecht's Threepenny Opera, as well as the subsequent 1931 film by Georg Wilhelm Pabst. He also appeared in the movie, Kuhle Wampe.
