Teatro Arthur Azevedo, Theatre in São Luís, Brazil.

Teatro Arthur Azevedo is a theater in São Luís featuring neoclassical architecture spread across multiple floors with ornate interior spaces. The building holds 750 audience seats and 6 special tribune seats, along with entrance halls, stage areas, noble rooms, and costume facilities.

The building was constructed in 1816 and opened in 1817 as Teatro União before undergoing several name changes over time. It was eventually renamed to honor Brazilian playwright Arthur Azevedo and his contributions to the nation's theatrical tradition.

The theatre carries the name of Maranhão playwright Artur de Azevedo (1855–1908), adopted in the 1920s; it was earlier called Teatro União and Teatro São Luiz. Its Núcleo Arte-Educação, run with the state education secretariat, offers theatre, dance, choral singing and piano courses to public school pupils, and the venue opens special sessions on commemorative dates.

The auditorium is arranged over orchestra seats, frisas, boxes, balconies and galleries, with 750 seats for the public plus 6 in the tribune for authorities. The building also holds foyers, a bar, dance and choir rooms, carpentry and a costume workshop, so allow time to find your level before the performance.

Apolônia Pinto was born in 1854 in Wardroom No. 1, where her Portuguese actress mother went into labour during a performance. By twelve she was winning audiences in "A Cigana de Paris". Two plaques in that same dressing room, a bronze bust and her remains kept in the building honour her.
