Teatro São João, Cultural heritage theatre in Sobral, Brazil.

Theatro São João is a theatre building in central Sobral, listed by IPHAN, Brazil's national heritage institute. It was built for the Sociedade Cultural União Sobralense, the cultural society founded in 1875 to promote the city's cultural development, and its stage has hosted theatrical performances since its opening in 1880.

The Sociedade Cultural União Sobralense founded the theater in 1875, opening it in 1880 with a theatrical performance. Major renovation work took place in 2004, bringing the structure up to modern standards while respecting its original elements.

The theatre's name honours São João, and its 1880 opening featured the comedy-drama A Honra de um taverneiro by Correia Vasques, performed by amateur actors from Sobral. When it reopened in 2004, the programme echoed that debut with Samuel Beckett's Esperando Godot, directed by Chico Expedito after about five months of preparation. The cast included actors linked to Sobral's theatre scene since the 1970s and 1980s, among them Rogênio Martins and Sérgio Presley.

The theater sits at a central plaza in the city, making it easy to locate and access on foot. Check ahead about upcoming events, as the performance schedule varies by season throughout the year.

The 2004 reopening echoed 1880: both were marked by a theatrical performance. In 1880 amateur actors from Sobral staged Correia Vasques's comedy-drama A Honra de um taverneiro; in 2004 the chosen play was Samuel Beckett's Waiting for Godot, directed by Chico Expedito after about five months of preparation with a cast of veteran Sobral actors.
