San Giovanni in Bragora is a church in Venice, Italy, located in the sestiere of Castello.

Pietro Barbo, future Pope Paul II, and Antonio Vivaldi were baptised in the church.

The interior houses works by Cima da Conegliano (Baptism of Christ, 1492 and St. Helena and Constantine at the Cross, 1501-1503) and Alvise Vivarini and has a trussed ceiling.

It could derive from the Greek agorà (square), referring to the campo facing the church, or from the dialect bragora ("market") or bragolare ("fishing").

It could also be from the word brago, meaning mud, on account of the former swampy state of islands of Venice.
