Agostino Barbarigo (or simply Barbarigo) is the name of at least three ships of the Italian Navy, named in honour of Agostino Barbarigo (1419–1485), the 73rd Doge of Venice. The name has been borne by the following vessels:

Additional note
A merchant ship named Barbarigo (approx. 5,300 GRT) was also built in 1930 at Monfalcone and lost during World War II, though this was a civilian vessel rather than a warship.
All three naval vessels are named after Agostino Barbarigo, the Venetian doge who commanded the Venetian fleet at the Battle of Zonchio (1499) and later served as Doge from 1485 to 1501.
