The Grand Opera House is a theatre in Belfast, Northern Ireland, designed by the most prolific theatre architect of the period, Frank Matcham. It opened on 23 December 1895.
According to the Theatres Trust, the "magnificent auditorium is probably the best surviving example in the United Kingdom of the oriental style applied to theatre architecture".
The building has been damaged by bombs on several occasions, usually when the nearby Europa Hotel had been targeted. It was badly damaged by bomb blasts in 1991 and 1993. The theatre continued, however, to host musicals, plays, pantomimes and live music.
