Caitlen is Irish in Origin.

Caitlen is a modern respelling of Caitlin/Caitlín, the Irish form of Catherine, derived from Greek Aikaterine. In Irish, Caitlín is pronounced “KAT-leen,” while contemporary English spellings are typically “KATE-lin,” a pronunciation Caitlen shares. The name is commonly interpreted as “pure,” tracing to Greek katharos, though scholars note the ultimate origin of Aikaterine is uncertain and may predate that meaning.

The Catherine/Caitlín tradition reached Ireland via Norman French in the Middle Ages and remained steady through devotion to saints such as Catherine of Alexandria and Catherine of Siena. Caitlin-based spellings surged across the English-speaking world from the 1970s to early 2000s. Caitlen fits alongside variants like Caitlín, Caitlin, Caitlyn, Kaitlin, Kaitlyn, Katelyn/Katelynn, Katelin, Catelyn, and Catlin, but remains relatively uncommon. Nicknames and short forms include Cate, Cat, Cady, Katie, and Kit.
