Cluj-Napoca Hungarian Opera, Opera company in Cluj-Napoca, Romania

The Cluj-Napoca Hungarian Opera is a public opera company founded on 17 December 1948, performing in the Hungarian Theatre of Cluj, a building constructed in 1909–1910 on the site of an old summer theatre and reconstructed in 1959–1961. The venue seats up to 862 people.

The company opened on 11 December 1948 with Kodály's Háry János in the Sétatér theatre building, sharing the roof with the Hungarian Theatre of Cluj. The structure itself was built in 1909–1910 on the site of an old summer theatre and reconstructed in 1959–1961. Its first seasons staged Smetana's The Bartered Bride, Erkel's Bánk bán and Donizetti's Don Pasquale.

The company opened on 11 December 1948 with Kodály's Háry János, sharing the State Hungarian Theatre building. Its founders aimed at a "people's opera", staging works such as Erkel's Bánk bán and Kodály's Székely fonó. Later directors added Verdi, Puccini and Bartók, whose three stage works entered the repertoire in 1964–65.

The opera shares the Hungarian Theatre of Cluj building, which seats up to 862 people. Performances are staged in that auditorium rather than in a separate opera house, so check which company is playing before booking. The building stands on the site of an old summer theatre and was reconstructed in 1959–1961.

Between 1959 and 1961 the building underwent major reconstruction to improve its technical systems while keeping its original character intact. This careful renovation allows visitors to experience both the historic structure and contemporary performance capabilities.
