Cathmore is Irish, Scottish Gaelic in Origin.

Cathmore is a rare masculine given name of Irish and Scottish Gaelic origin, from Old Irish cath “battle” + mór “great,” meaning “great in battle” or “great warrior.” In Gaelic it appears as Cathmór and is often anglicized as Cathmor (notably in 18th‑century texts); the modern Cathmore follows English spelling. Related Gaelic names with similar semantics include Cathal (“battle ruler”) and Cormac.

The name occurs in early Gaelic tradition as an epithet and is best known from James Macpherson’s Ossianic poems (1760s), where Cathmor is a heroic king. It never became common in parish or civil records but has seen occasional revival during the Celtic Romantic and later Gaelic‑renaissance periods, sometimes as a middle name. Variants are limited to spelling: Cathmór, Cathmor, and Cathmore; diminutives are rare, though Cath or Mor may serve informally. The overall tone is martial and heroic, appealing to families seeking a distinctive Gaelic heritage choice.
