Enide or Enid is a character from Arthurian legend. She is Erec's wife in Chrétien de Troyes' Erec and Enide, and Geraint's in the Welsh Romance Geraint and Enid, analogous to Chrétien's version.

Enide and Geraint/Erec meet while the hero is on a mission to defeat a cruel knight, and her family provides him with armor and food. They fall in love and marry, but the hero begins to forsake his social and chivalric duties for domestic bliss. Rumors spread, and Enide blames herself. One night, her husband overhears her crying about damaging his reputation.

In Chrétien's version, Erec begins to question Enide's love, but in Geraint the protagonist misunderstands her sobs and thinks she has been unfaithful to him. In both romances, the hero makes her accompany him on a long and dangerous trip, and forbids her to talk to him. Enide ignores this command several times to warn her husband of impending danger. Over the course of the trip, Erec/Geraint proves his abilities as a knight have not faded and accepts that Enide's love and loyalty are genuine, and the couple is reconciled.
