Belarusian State Musical Theatre, Musical performance venue in Minsk, Belarus.

The Belarusian State Musical Theatre is a performing arts venue in Minsk with a permanent ensemble of singers, dancers, and musicians. The building houses a main auditorium and presents a rotating programme of ballet, opera, and musical productions across its season.

Founded in 1970 as the State Theatre of Musical Comedy of Belarus, it opened its first season on 17 January 1971 with Yuri Semenyako's "The Skylark Sings". For a decade the troupe had no home and performed on borrowed stages. In 1981 it moved into its own building at 44 Myasnikova Street, opening its twelfth season there on 15 October with Johann Strauss's "Die Fledermaus". It was renamed the Belarusian State Musical Theatre in 2000, received the title Honoured Collective of the Republic of Belarus, and became academic in 2009.

The theatre is known for staging operettas alongside musicals and ballet, making it one of the few venues in the city where these genres share the same stage. Audiences tend to be mixed, drawing both regular theatergoers and people attending a live show for the first time.

The programme changes throughout the season, so checking what is on before visiting helps avoid disappointment. Booking in advance is a good idea for popular productions, as the auditorium can fill up quickly.

The building dates from July 1981, not the 1970s. The lead architect was A. Tkachuk, with U. Tarnouski and engineer V. Katsnelson on the team. Above the main entrance, bronze sculptures of the Muses by L. Zilber sit on corbels, and a fountain with decorative masks by M. Belyaev stands in front.
