San Martino, Roman Catholic church in Burano, Italy.

San Martino is a 16th-century church on Burano in the Venetian lagoon. Its unfinished exterior has a gabled central section flanked by two lower side wings. Inside, a vaulted ceiling covers a Latin-cross plan with three naves, a transept, two side chapels and a main chapel; a pneumatic organ by Vincenzo Mascioni (1913) stands on the counter-facade.

San Martino was built in the 16th century and reconsecrated in 1645, the date the sources give for its renewed dedication. Its bell tower is attributed to Andrea Tirali, who built it between 1703 and 1714 to a height of 53 metres. Settlements that began during construction worsened until after the Second World War, and the Fondedile firm of Naples, led by engineer Fernando Lizzi, consolidated the tower in works completed in 1970.

The church holds a notable painting by Giambattista Tiepolo that reflects how Venetian artists depicted religious scenes. The work remains visible to visitors today and offers insight into the artistic traditions of the lagoon.

The church is accessible by water-bus line 12, which travels to Burano station. Visitors should plan ahead, as opening hours are limited and vary throughout the day.

The church lacks a conventional main entrance on its front facade and instead features a lateral portal in Renaissance style. This unusual arrangement makes the building an interesting example of local architectural choices.
