Giacomo II Crispo (or Jacopo) (d. 1447) was the thirteenth Duke of the Archipelago, etc., from 1433 to 1447.
He was the son of twelfth Duke John II Crispo and Nobil Donna Francesca Morosini, Patrizia Veneta. He was a minor when he succeeded to the throne, and during his minority, he was under the guardianship of his mother Francesca, described as a "masterful woman", who continued to influence in the affairs of state during the reign of her son and grandson until the accession of William II to the throne in 1453, while the Duchy was ruled by his uncles William and Nicholas.[1]

He married in 1444 Ginevra Gattilusio, daughter of Dorino I of Lesbos, and wife Orietta Doria, and had two children:
