Teatro Paulo Eiró, Municipal theatre in Santo Amaro, São Paulo, Brazil

Teatro Paulo Eiró is a modern-architecture theatre in Santo Amaro, São Paulo, designed by Roberto Tibau and opened in 1957. Its auditorium seats 467: 281 on the ground floor, 166 in the upper balcony and 20 adapted seats. Unlike other municipal theatres, it has an orchestra pit, and a hydraulic lift at the proscenium allows opera staging.

Roberto Tibau designed the building in the 1950s, and it opened in 1957 in the Santo Amaro district. The venue was created to meet growing demand for cultural facilities in the city's southern area.

The theatre is named after Paulo Eiró, a poet, writer, playwright and teacher from Santo Amaro when it was still a separate municipality. In 1968 a tribute to him was held and the sculptor Júlio Guerra's panel Homenagem às Artes was installed in front of the building. Since February 2017 the venue has been the official artistic residence of the Orquestra Filarmônica Santo Amaro.

The 2011 renovation added an orchestra pit with a hydraulic lift at the proscenium, making opera staging possible, and improved acoustics, electrical and hydraulic systems. Of the 467 seats, 281 are on the ground floor, 166 on the upper balcony and 20 are reserved and adapted for people with disabilities or reduced mobility. An elevator was installed and the dressing rooms enlarged.

The exterior facade features a large-scale mosaic created by artist Júlio Guerra that honors a local poet. This artwork immediately catches visitors' eyes and gives the building a distinctive visual identity.
