History & Origin

Kalen is a short, modern-feeling name with more than one possible source: the Irish Caolan ('slender'), the name Kellen, or a fresh coinage. All of those lean male, and its use for a girl is recent and rare. We flag the lean and the uncertainty honestly rather than choose a tidy story (said 'KAY-lun').

For girls it appears only rarely in the U.S., against heavier boys' use. Rare, short, and unisex-feeling.
