Donata Badoer (c. 1280 – between 1333 and 1336) was an Italian noblewoman from the Republic of Venice.

Belonging to an ancient Venetian patrician family named Badoer, she was daughter of merchant Vitale Badoèr. In 1300 she married Marco Polo, the Venetian explorer, son of Niccolò Polo. From the union three daughters are born: Fantina, Belella and Moreta Polo.
