Teatro Pedro II, Opera house in Ribeirão Preto, Brazil.

Teatro Pedro II is an opera house on Praça XV de Novembro in Ribeirão Preto, part of the Quarteirão Paulista complex. Its eclectic facade has a central section inscribed "THEATRO PEDRO II" above three tall arched windows separated by columns, with balconies on the left and a segmental pediment above. The auditorium seats 1,588 and the building covers 6,500 m².

The theatre was commissioned by the Cia. Cervejaria Paulista to anchor the "Quarteirão Paulista" facing Praça XV de Novembro. Architect Hippolyto Gustavo Pujol Júnior designed it between 1928 and 1930, with the German firm Kemmitz handling the structure. It opened on 8 October 1930 with the film "Alvorada do Amor", seating 2,000, and its name, honouring Emperor Pedro II, was chosen by readers of the newspaper A Cidade.

The theatre's name was chosen by a public competition run by the newspaper A Cidade, honouring Brazil's last emperor, Dom Pedro II. Between the 1950s and 1970s its basement housed carnival balls and, outside carnival, a gaming room known as the "Caverna do Diabo" (Devil's Cave). Secret passages linked it to the neighbouring hotels, used by the city's elite.

The theatre stands on Praça XV de Novembro, at the corner of Rua Duque de Caxias and Rua Álvares Cabral, in the Quarteirão Paulista ensemble. The main entrance is recessed behind a stone balustrade balcony, reached from the square. The auditorium holds 1588 spectators, and the orchestra pit lift seats about sixty musicians.

The stage house was lowered by six metres during the 1990s restoration, and a new basement with two levels was dug out for scenery workshops, carpentry and technical storage. The orchestra pit has a lift and holds about sixty musicians. The metal dome over the auditorium was rebuilt, and a new dome by artist Tomie Ohtake was installed.
