Lehártheater, Opera house and theater in Bad Ischl, Austria

Lehártheater is an opera house and theater in Bad Ischl featuring traditional seating with boxes and rows for various types of performances. The building accommodates theatrical productions, operettas, and film screenings throughout the year.

Built in 1826–27 by salt-works architect Franz Ferdinand Edangler on a plot provided by Franz Wirer, it replaced the attic theatre of painter Lukas Krall and opened as the Ischler Kurtheater. It was enlarged in 1865, given a separate imperial-box entrance in 1882 and electric lighting in 1904. It has borne the name Lehártheater only since 1940.

The venue is named after composer Franz Lehár and serves as a gathering place for music enthusiasts visiting the spa town. Performances here reflect the local tradition of operetta and classical music that has shaped the town's identity.

The building is centrally located in Bad Ischl and easily accessible on foot from the town center. Visitors should check the current program in advance and reserve tickets ahead of time.

The theatre was renamed Lehártheater in 1940, not at its founding; it opened in 1827 as the Ischler Kurtheater. Johann Strauss and Franz Lehár both conducted here, and a bust of actor Helmut Berger was unveiled at the entrance in May 2019 for his 75th birthday.
