Teatro Comunale, Municipal theater in Sassari, Italy.

The Teatro Comunale is a performance hall in Sassari with roughly 1,400 seats arranged on multiple levels. The building stands in the Art Nouveau district of Cappuccini alongside a church and conservatory.

The project was launched in 1984 under mayor Raimondo Rizzu to replace the smaller Teatro Verdi. Work began in 1990 under Sassari architect Elia Lubiani and lasted about twenty years due to scarce funding. On 25 October 2007, with the site near completion, an unexplained fire hit the audition hall and roof. It opened informally on 21 February 2012 with President Giorgio Napolitano present, and was definitively inaugurated on 12 October 2012 with Gounod's Romeo et Juliette.

The theatre's seasons are run by two organisations: the Ente Concerti Marialisa de Carolis stages the opera season, while Cedac organises the prose season. The house was formally opened on 12 October 2012 with Gounod's opera Romeo et Juliette.

The theater stands on the piazza beside the Cappuccini church and the Luigi Canepa Conservatory, in the Cappuccini district. An underground car park with 470 spaces is being completed for the building. Visitors have long reported poor sightlines from some rows, especially the front rows of the gallery, and cold draughts in winter despite powerful heating.

The theater is part of an arts center that also includes the Luigi Canepa Conservatory and the Cappuccini Church. These three institutions form a hub of artistic and musical activity together.
