Theater Eisleben, Municipal theater in Lutherstadt Eisleben, Germany.

Theater Eisleben is a theatre in Lutherstadt Eisleben with two stages: the Großer Saal seats 385 spectators, and the Foyerbühne has 96 seats. It has been directed by Intendant Ulrich Fischer since 1994.

The Theater Eisleben was re-founded on 13 July 1945 by Felix Ecke, who wrote under the pseudonym Ralph Wiener, as the first new German theater after World War II. Originally a private civic stage, it was nationalized in 1953 and renamed Thomas-Müntzer-Theater. In 1960 it took over the music theater division of the Stadttheater Köthen. After 1990 it dropped the Müntzer name and became Landesbühne Sachsen-Anhalt; staff fell from a peak of 222 to 70, and the music theater and orchestra were abandoned in 1993 for lack of funds.

The house stages around a dozen premieres a season on two stages, plus guest performances of music theatre, ballet, cabaret, readings and concerts. Its name changed in 1990: the Thomas-Müntzer label, seen as purely political, was dropped, and it performed as Landesbühne Sachsen-Anhalt.

The venue presents several productions each season for adults, young people, and children across different theatrical genres. Visitors should expect a varied program that includes premiere works throughout the year.

The house has been directed since 1994 by intendant Ulrich Fischer. In peak times it employed 222 people; by the 1990s the staff had fallen to 70 after the music theatre division and orchestra were given up in 1993 for lack of money.
