Bartolomeo Gradenigo (1263 – 28 December 1342) was the 53rd Doge of Venice from 7 November 1339 until his death.

[1] Born in Venice to an ancient noble family, he was a rich tradesman.

Gradenigo devoted to politics very early in his life, acting as podestà of Ragusa and Capodistria, as well as procuratore in the capital.

[2] His short reign was rather peaceful, apart from a revolt in Crete and some Turkish incursions.

The most important event was the tempest that struck against Venice on 15 February 1340 and which, according to legend, was pushed back only through the supernatural intercession of St. Mark, St. George and St. Nicholas, brought to the lagoon by a humble fisherman.
