Cairan is Irish in Origin.

Cairan is a modern respelling of the Irish Gaelic Ciarán, from Old Irish ciar (“dark, black, dusky”) plus the diminutive -án, giving the meaning “little dark one” or “dark‑haired little one.” In Ireland the traditional form uses the accent (Ciarán), while Ciaran and Kieran are the most common Anglicizations. The name has long been favored across Ireland and Scotland and has spread broadly through the English‑speaking world.

Early prominence comes from two revered 5th–6th‑century saints: Ciarán of Saigir and Ciarán of Clonmacnoise, whose cult helped cement the name’s popularity in medieval monastic and later parish registers. Variants include Ciarán, Ciaran, Kieran, Kieron, Keiran, and Kyran; related feminine forms are Ciara, Keira/Kiera, and Kira. Note that Kiran, though similar in sound, is a separate Indian name from Sanskrit kiran “ray of light,” not etymologically connected to Cairan.
