Macartan is Irish in Origin.

Macartan is the Anglicized form of the Old Irish name Mac Cairthinn (also Mac Cairthín), literally “son of Cairthinn.” Cairthinn is connected with modern Irish caorthann “rowan tree” (from caor “berry, blaze”), yielding the evocative sense “son of the rowan” or “of the bright one.”

Borne by the 5th‑century Saint Macartan, first bishop of Clogher and a close companion of Patrick, the name is anchored in Ulster’s early ecclesiastical tradition, surfacing in martyrologies and hagiography. As a given name it remained uncommon outside saintly commemoration but has seen modest modern revival in Ireland as a heritage choice. Variants and spellings include MacCartan; Irish forms Mac Cairthinn/Mac Cairthín; and the Latinized Macartanus. Note that the surname McCartan/MacCartan often arises instead from Mac Artáin, “son of Artán,” with Artán a diminutive of Art meaning “bear” or “champion” - a separate lineage sometimes conflated with the saint’s name.
