Catlyn is a modern English variant of Caitlin/Caitlyn, the Anglicized spelling of Irish Caitlín, itself the Gaelic form of Catherine (Greek Aikaterinē).

Longstanding associations with saints named Catherine reinforce its virtuous sense.

Carried across medieval Europe by the cult of St. Catherine, the name settled in Ireland as Caitlín and, from the late 20th century, spread widely in English-speaking countries through spellings like Caitlin and Caitlyn. Catlyn arose as a streamlined, less common alternative, preserving the familiar sound while offering a crisp look.
