Lamorak /ˈlæmərək/ (or Lamerak,[1] Lamorac(k), Lamorat, Lamerocke, and other spellings) is a Knight of the Round Table in Arthurian legend.

Introduced in the Prose Tristan, Lamorak reappears in later works including the Post-Vulgate Cycle and Thomas Malory's compilation Le Morte d'Arthur.

Lamorak reappears at a tournament and explains the situation to Arthur, but rejects the king's promise of protection at his court and enforcement of a truce between the two royal families.

The Italian La Tavola Ritonda features his uncle named Lamorat de Listenois, a brother of Pellinore.

He helps Tristan escape from the castle of the lustful fairy enchantress Medea, and is later accidentally killed by Dinadan's father known as the Good Knight Without Fear when the latter mistakes him for his enemy.
