John of Montfort (French: Jean; died 27 November 1283) was lord of Toron from 1257 to 1266 and Lord of Tyre from 1270 to 1283. He was the son of Philip of Montfort (lord of La Ferté-Alais, of Bréthencourt, of Castres, of Toron and of Tyre), and his second wife Maria of Antioch-Armenia (the elder daughter of Raymond-Roupen of Antioch and hence Lady of Toron and pretender of Armenia). In 1270 his father was killed by the Assassins, and John succeeded to the lordship and governed Tyre until his death in 1283. He had no children, so Hugh III allowed Humphrey of Montfort to succeed his brother.
