Florent of Hainaut (also Floris or Florence; Hainaut, also spelled "Hainault") (c. 1255 – 23 January 1297) was Prince of Achaea from 1289 to his death, in right of his wife, Isabella of Villehardouin.

The fall of the Angevins in Sicily meant that they were preoccupied with recouping territory there and few Western governments would send troops to defend Morea.

Florent thus made peace and maintained it until 1293, when the Greeks retook Kalamata.

Florent did not despair and did not reopen the war which had been ongoing until his succession: he instead sent an embassy in protest to Andronikos II Palaiologos, and the emperor returned Kalamata.

In 1296, the Greeks retook the castle of Saint George in Arcadia.
