Kalin

Meaning & origin

Kalin first appeared in U.S. birth records in 1959 and enjoyed a surge in popularity during the 1990s, reaching its peak rank in 1994. Since then, its usage has been on a steady decline, with a trajectory indicating a falling trend since 1995. In the most recent year (2025), Kalin ranked 6,143, making it a relatively uncommon choice: approximately 1 in 122,005 newborns received the name. The name exhibits a unisex appeal, though it has never been strongly associated with any particular region, as no top states are recorded. Kalin may be a modern respelling of traditional names like Kaelin or Kaylin, reflecting the late-20th-century trend of creating distinctive-sounding names through phonetic variation.

Kalin may derive from the Irish surname Kaelin, an Anglicized form of Ó Cathaláin, meaning 'descendant of Cathalán' (a diminutive of Cathal, 'battle ruler'). It also functions as a modern invented name, blending popular sounds like Kay- and -lin. Its usage as a given name in the United States dates to the mid-20th century, with a notable peak in the 1990s.
