Blacasset, Blacassetz, Blacssetz, or Blachessetz (fl. 1233–1242) was a Provençal troubadour of the noble family of the Blacas, lords of Aulps, in the Empire. He was probably a son of the troubadour Blacatz, as his vida alleges, though this has come into doubt. He was also distantly related to Charles I of Naples and Raymond Berengar IV of Provence. According to his vida, he was like his father in merit, good deeds, and munificence, and also reputed to be a good lover.
