Blacatz, known in French genealogy as Blacas de Blacas III (1165-1237), was feudal lord of Aups and a troubadour. Sordello composed a lament (planh) on his death, inviting the kings of his time to share and eat the heart of Blacatz and thus acquire a portion of his courage.
He was the father of the troubadour Blacasset.
