In the Vulgate Mort Artu, one of Mordred's two sons, probably the oldest. After Arthur's and Mordred's death, Melehan and his unnamed brother seized England.

In a battle with Lancelot's men on the plain of Winchester, Melehan killed Lionel but was then killed by Bors, while Lancelot slew Mordred's other son.

A son of Mordred named Melou appears in Layamon's Brut.
