Meaning & origin
Kaytlyn is a modern American invention that emerged in the mid-1980s as part of a wave of creative spellings of the enduringly popular Caitlin/Kaitlyn family. Its rank of 13208 in 2025 reflects a steep decline from its peak in 1998, when it was most frequently chosen. At its height, Kaytlyn enjoyed brief favor among parents seeking a distinctive twist on a classic. The name first appeared in Social Security records in 1985, and its trajectory has been falling ever since 1998. Although not concentrated in any particular state, the name has been used across the United States. As a respelling, Kaytlyn carries the same meaning as its root: 'pure.'
Kaytlyn is a modern invented spelling of Caitlin, itself the Irish form of Catherine, which ultimately derives from Greek Aikaterine.
