Teatro Castro Alves, Theatre in Salvador, Brazil.

The Teatro Castro Alves is a major cultural venue in Salvador, featuring a main auditorium with capacity for over 1,500 (one thousand five hundred) spectators and multiple performance spaces designed for theater, music, and dance events.

The theatre was designed in 1948 by Alcides da Rocha Miranda and José de Souza Reis, but the built version by José Bina Fonyat Filho and engineer Humberto Lemos Lopes won the IV Bienal de São Paulo. A fire on 9 July 1958, five days before the planned opening, destroyed the building; reconstruction stalled under Juracy Magalhães and was completed under Lomanto Júnior. It opened on 4 March 1967 with President Castelo Branco present, and after a second fire and closure in 1989 it reopened on 27 March 1993 following a US$10 million renovation.

The theatre is named after the poet Antônio de Castro Alves, known as the "Poet of the Slaves". In the late 1960s Gilberto Gil and Caetano Veloso performed here, part of the cultural upheaval that started in Bahia and spread across Brazil in the 1970s. The Sala do Coro, once used for opera chorus rehearsals, now prioritises local theatre productions.

The theatre stands on the Largo do Campo Grande, in Salvador. Its complex comprises the Sala Principal, the Sala do Coro and the Concha Acústica, each with its own entrance and capacity. Tickets went on sale online and by phone from 2014, an innovation for the venue.

The venue houses the Bahia Symphony Orchestra and the Castro Alves Theatre Ballet, the first public dance company in the North and Northeast regions of Brazil, with a repertoire exceeding 70 (seventy) dance productions.
