Kellen is Irish in Origin.

Kellen is a modern English given name with two main roots. In Irish contexts, it aligns with Kellan/Keelan, Anglicizations of the Gaelic Caolán (from caol, “slender; narrow”), yielding the sense “slender one.” It also arises from the Germanic/Dutch surname Kellen, a toponym from places named Kellen, likely derived from words meaning “basin” or “marshy hollow,” giving a topographic reading like “dweller by the marsh.”

Used occasionally in the U.S. since the mid-20th century, Kellen entered wider circulation in the 1970s and 1980s and spiked in the 2000s, helped by athletes such as Hall-of-Famer Kellen Winslow and the visibility of the variant Kellan in pop culture. It is predominantly masculine but sometimes treated as unisex. Common variants and spellings include Kellan, Kellin, Keelen, and, via the Gaelic route, Keelan and Caolán; short forms include Kel.
