Peter, Lord of Conches and Mehun

Peter of Courtenay (c. 1218–1250), lord of Conches and Mehun, was the eldest son of Robert I of Courtenay, lord of Champignelles, and Mahaut of Mehun. He ruled his Norman and Berry lordships from 1239, and on 25 August 1248 sailed from Aigues-Mortes with his cousin Louis IX on the Seventh Crusade to Egypt.

Most historians place his death at Mansurah on 8 February 1250, when Robert I of Artois led a vanguard into a Mamluk trap. His daughter Amicia by Pétronille of Joigny married Robert II of Artois.
