Jacopo Tiepolo (shortly before 1170 – 19 July 1249), also known as Giacomo Tiepolo, was Doge of Venice from 1229 to 1249. He had previously served as the first Venetian Duke of Crete, and two terms as Podestà of Constantinople, twice as governor of Treviso, and three times as ambassador to the Holy See. His dogate was marked by major domestic reforms, including the codification of civil law and the establishment of the Venetian Senate, but also against a mounting conflict with Emperor Frederick II, which broke into open war from 1237 to 1245.
