Wife of King Ban and mother of Sir Lancelot. After the death of her husband and the appropriation of her young son by Viviane, Queen Elaine founded a religious house, the Royal Minster, on the scene of her losses in Benwick and lived there for many years as a saintly woman. This we find in the Vulgate. Malory only records that Merlin, visiting her, assured her she would live long enough to witness her son's fame and glory.

She visited her nephews Bors and Lionel when they were in Gaul during Arthur's wars against King Claudas. From her nephews she got news of her son. Later, when the war was won, she visited Lancelot himself in Gannes, afterward returning to her minster.

Her sister was Evaine, who married Ban's brother Bors.
