Lú is an Irish given name, the modern form of Old Irish Lug/Lugh, the prominent Celtic deity of skill, crafts, and sovereignty, whose name underlies the county name Louth (Contae Lú) and the harvest festival Lughnasa/Lúnasa. Etymology is debated: some derive it from Proto-Celtic *lug- “oath, pledge” (PIE *leugh-), while popular lore links it to “light, brightness” (PIE *leuk-). Either way, the mythic associations give Lú a meaning shaded by brilliance, mastery, and sworn bonds.

Usage as a personal name in Ireland has been rare, but related medieval forms such as Lugaid/Lugaidh (modern Lughaidh, often anglicized Louie) were widespread. Cross-Celtic cognates and variants include Lugh, Lug, Lugus (Gaulish) and Welsh Lleu (as in Lleu Llaw Gyffes). In Lusophone and Hispanophone contexts, Lú also appears as an affectionate short form for Lu‑ names (Luís/Luiz, Lúcia/Lucía, Luana, etc.).
