Celtic Name Generator: Names From Myth and the Old Tongues

The Sound of the Celtic World

Celtic names carry an ancient, musical quality drawn from the Irish, Scottish and Welsh traditions (plus Cornish, Breton and Manx): names rich in meaning, often tied to nature, gods and old legends. A Celtic name generator draws on real traditional names such as Aoife, Cormac and Rhiannon, with optional meaning hints, so your characters feel rooted in myth rather than invented from nowhere.

The spelling is part of the magic and the challenge. Gaelic spelling follows its own rules: in Irish, "mh" and "bh" usually sound like "v", so Niamh is said roughly "neev". That gives the names their distinctive look, and sometimes calls for a gentle pronunciation note for your audience.

Myth and Meaning

Celtic naming is steeped in mythology and the natural world. Oisín, the poet-warrior son of Fionn mac Cumhaill, has a name meaning "little deer", after the legend of his mother's enchantment. That heritage makes Celtic names a natural fit for fantasy, where their built-in sense of ancient story lends instant depth to a character or a place.

The tradition spans related but distinct cultures: linguists split the living Celtic languages into a Goidelic branch (Irish, Scottish Gaelic, Manx) and a Brythonic branch (Welsh, Cornish, Breton), so an Irish-flavored name sounds different from a Welsh one. If your setting leans toward one branch, leaning into its sounds keeps the names coherent rather than a generic Celtic blur.

Using the Names

Celtic names suit fantasy fiction, historical stories set in the Celtic world, and games drawing on that mythic atmosphere. Read candidates aloud and keep the ones that sound suitably ancient and lyrical. For nature-priest characters, our druid name guide builds on the same roots.

Generated names are free to use, though it is a courtesy to check that a full name does not match a real public figure. To lean toward a specific branch, pair the Celtic generator with an Irish name generator or a Scottish name generator, which add surnames.
