Catlyn

Catlyn is a feminine name representing a modern variation of Caitlin, which itself derives from the Irish name Caitlín, a form of Katherine ultimately meaning "pure." This streamlined spelling emerged in the late 20th century as parents sought alternatives to the numerous Caitlin/Kaitlyn variants that peaked in popularity during the 1980s and 1990s. The simplified form maintains the familiar pronunciation while offering a more visually straightforward option. Though never reaching the heights of its spelling variants, Catlyn has maintained steady if modest usage since the 1990s. The name carries a youthful, contemporary feel while still connecting to its traditional Irish roots and projecting a balance of strength and femininity.

Pronounced KAT-lin.

As of October 2026, Catlyn ranked #16167 in US births in 2018 SSA, peaked at #3100 in 1996.
