Arbisteatern (The Arbis theatre) in the city of Norrköping, Sweden, is the country's oldest amateur theatre stage, famous for productions where professional actors and amateurs work together.

Many plays, operettas and musicals have been produced in the theatre, but also revues and variety shows.

Gideon Wahlberg managed the theatre between 1918-1931 and 1933–1934, and many of his shows were also performed there.

Between 1964 and 2001, Arbisteatern was the home of Norrköping's Operetta Society.

[1] In 2012, the theatre briefly closed but soon re-opened with new artistic direction.
