Meaning & origin

Kaytlin is a modern respelling of the Irish name Caitlin, which means 'pure'. It first appeared in U.S. records in 1984 and reached its peak in 1999, reflecting the late 1990s popularity of similar names like Katelyn and Caitlin. Since 1999, its usage has fallen steadily, and in 2025 it did not appear in the top 1000 names. The name is primarily given to girls and remains part of a trend of unique spellings for traditional names. While Kaytlin has no strong ties to any specific region or top states, its trajectory mirrors that of many creative spellings that rose and fell in the 1990s and 2000s.

Kaytlin is a modern respelling of Caitlin or Katelyn, which itself derives from the Irish name Caitlín, the Irish form of Katherine. The name Katherine ultimately comes from the Greek Aikaterine, with the meaning 'pure' popularized by early Christian saints. Kaytlin emerged in the United States in the late 20th century as part of a trend of creative spellings for popular names like Caitlin. Its peak year was 1999, reflecting the broader popularity of similar-sounding names at that time.
