The Stadttheater Bremerhaven (Bremerhaven municipal theatre) is a theatre in Bremerhaven, Germany.
Founded in 1867, it serves three genres: opera and other musical theatre, spoken plays, and dance.
A theatre built on the present site in 1911 was largely destroyed in World War II; a new house was built in 1952 which incorporated the surviving Jugendstil facade.
The smaller Bürgerhaus Lehe, which served as a home before the rebuilding, is currently used as a venue for chamber pieces.
