Kaetlyn

Kaetlyn is a contemporary feminine spelling variation of Caitlin, which ultimately derives from the Irish name Caitlín, a form of Katherine. The distinctive spelling with 'ae' and 'y' gives this classic name a modern twist while maintaining its traditional pronunciation. Katherine itself comes from the Greek name Aikaterine, associated with meanings of 'pure' or 'clear.' Kaetlyn began appearing more frequently in the late 1990s and 2000s, during a period when parents increasingly sought alternative spellings for traditional names. The popularity of figure skater Kaetlyn Osmond has brought additional recognition to this spelling variant in recent years.

Pronounced KATE-lin.

As of October 2026, Kaetlyn ranked #16685 in US births in 2019 SSA, peaked at #2343 in 1997.
