Lugh is Gaelic, Irish in Origin.

Rooted in Old Irish Lug and Proto-Celtic *Lugus, Lugh is the name of the pan-Celtic god of many skills (Lugh Lámfada, “of the Long Arm”) and names the harvest festival Lughnasa/Lúnasa. The theonym underlies place-names such as Lugdunum (modern Lyon). Its precise meaning is debated: many connect it to the Indo-European root *leuk- “light, brightness,” yielding senses like “shining one,” while others relate it to an ancient term for “oath” or sacred pledge. A close Brittonic cognate appears in Welsh as Lleu.

Usage as a personal name is rare but saw revival with Celtic literary interest and Irish cultural nationalism, and today persists among families honoring Gaelic heritage or mythic symbolism. Variants and related forms include Lug (simplified), Lugus (Latinized), Welsh Lleu, and the Irish Lughaidh/Lughaí (often pronounced LOO-ee), which historically overlaps in tradition. Typically masculine, though sometimes chosen unisex in modern contexts.
