Meaning & origin
Kayleen entered U.S. birth records in 1934 and has since been used as a feminine given name. It reached its peak popularity in 2010, when it ranked 2,514th; by 2025 it had fallen into declining usage, reflecting a broader shift away from creatively-spelled -leen names. The name has been most common in Texas and California, states known for diverse naming trends. Kayleen's 1-in-22,961 frequency in 2025 places it well outside the mainstream, appealing to parents seeking a distinctive but familiar-sounding choice.
Kayleen is a 20th-century coinage, formed by combining Kay (often a short form of Katherine) with the popular feminine suffix -leen (derived from names like Eileen or Kathleen). It first appeared in birth records in the 1930s and gained modest use through the remainder of the century, peaking around 2010.
