John Chauderon

John Chauderon (French: Jean Chauderon; died 1294) was the Baron of Estamira and Grand Constable of the Principality of Achaea, the strongest of the principalities of Frankish Greece. He succeeded his father, Geoffrey Chauderon, in 1278. He married Guillerme, a daughter of Richard Orsini.

In 1292 or 1293, he went on a diplomatic mission to the Byzantine court in Constantinople along with Geoffrey of Aulnay, where they secured the recovery of the fortress of Kalamata, which had shortly before been seized by local Slavs and handed over to the Byzantine governor of Mystras.

After his death in 1294, he was succeeded as Grand Constable by his brother-in-law Engilbert of Liederkerque.
