Mythology & Literature Names · Guide
Celtic mythology baby names from Irish and Welsh legend, from Finn and Brigid to Rhiannon and Bran, with their meanings.
Few naming traditions carry as much atmosphere as the myths of the Celtic world. The old stories of Ireland and Wales are full of luminous gods, shape-shifting queens, warriors who could not be beaten, and doorways to an Otherworld just out of sight. Those tales left behind a treasury of names that still sound striking today: lyrical, ancient, and quietly powerful. If you are drawn to a name with a story behind it, Celtic mythology is one of the richest wells you can draw from. This guide walks through the gods, goddesses, and legendary figures worth knowing, explains what their names mean in plain English, and points out which ones a modern child can wear comfortably. You can explore the wider collection any time on our Gaelic baby names hub.
What makes a Celtic mythological name feel different from an ordinary vintage revival? The answer is layered meaning. These are not names that simply sounded pleasant to a distant ancestor. Each one is stitched into a body of narrative that survived for more than a thousand years, first spoken aloud by poets and only much later written down. The Irish tales cluster into great cycles, among them the Mythological Cycle and the Ulster Cycle, while the Welsh material is best known from the medieval collection of tales called the Mabinogion. A name pulled from those pages arrives carrying its whole world with it.
There is also the sound. Celtic languages tend toward soft consonants, open vowels, and a gentle music that suits the modern ear beautifully. Many of these names have short, wearable forms hiding inside longer, grander ones. And because the original spellings often include accent marks and letter combinations that look unfamiliar in English, most have settled into simple phonetic versions that travel easily. Throughout this guide the meanings and spellings are given in plain English so you can weigh each name on its own merits. When a name catches your eye, our names by meaning tool lets you find others that share the same idea, whether that is light, radiance, or courage.
Before we meet the figures one by one, it helps to see how a handful of the most familiar Celtic myth names sit in terms of everyday use today. Some have become genuinely common, while others remain rare and waiting to be rediscovered.
The takeaway from the chart is encouraging for anyone who wants distinctiveness. Only Finn has crossed fully into the mainstream. Names like Brigid, Rhiannon, and especially Bran are still uncommon enough that a child is unlikely to share one in a classroom, yet each is instantly pronounceable and steeped in story. That combination of familiarity and rarity is exactly what makes this category so rewarding.
The oldest layer of Irish myth centres on the Tuatha De Danann, a race of gods and skilled beings said to have ruled Ireland before mortal people arrived. Their names are among the most evocative in the whole tradition. Alongside them stand the warriors of the heroic cycles, chief among them Finn and Cu Chulainn, whose exploits filled the imaginations of storytellers for centuries. The table below gathers the major figures and what their names mean.
| Name | Meaning | Who they are |
|---|---|---|
| Lugh | Light, brightness | A radiant god of skill, craft, and the harvest |
| Finn (Fionn) | Fair, white, bright | Legendary leader of the warrior band the Fianna |
| Bran | Raven | A hero-voyager to the Otherworld; also a famous hound |
| Cu Chulainn | Hound of Culann | The unbeatable young champion of Ulster |
| Dagda | The good god | Father-figure of the Tuatha De Danann, keeper of a magic cauldron |
| Nuada | Cloud-maker, catcher | A king of the gods, later given a silver arm |
| Ogma | Linked to eloquence and writing | God of speech, said to have devised an early Irish script |
Of these, Finn is the runaway favourite for modern use, and it is easy to see why. It means fair or bright, it is short and confident, and it has already been adopted widely enough to feel normal without feeling overused. Lugh is more of a leap on the page, though it is pronounced simply as "Loo" and gave its name to the summer festival of Lughnasadh. Bran is a small, dark gem of a name meaning raven, spare and atmospheric. Cu Chulainn and the Dagda are magnificent characters but function better as inspiration than as everyday first names. If you love this heroic register, the full sweep of related choices lives on our Gaelic baby names collection, and you can compare them beside other traditions on the baby names by origin hub.
Many Celtic god-names describe light or brightness: Lugh, Finn, and Aine all circle the same idea. If a luminous meaning appeals to you, that theme runs right through the tradition and gives you a natural way to link a sibling set together.
The goddesses of Celtic myth are, if anything, even more compelling than the gods. They range from radiant figures of sovereignty and fertility to fearsome shapers of fate and war. Several of their names have quietly entered wider use, carried along by music, literature, and a growing appetite for names that sound both ancient and strong. Here are the ones worth knowing.
| Name | Meaning | Who they are |
|---|---|---|
| Brigid | Exalted, high one | Goddess of poetry, healing, and smithcraft; later a beloved saint |
| Rhiannon | Great queen, divine queen | A Welsh goddess-figure linked to horses and birds |
| Danu | Divine mother, flowing one | Ancestral mother of the Tuatha De Danann |
| Morrigan | Great queen, phantom queen | A shape-shifting goddess of war and fate |
| Aine | Radiance, brightness | Goddess of summer, love, and the sun's warmth |
| Epona | Divine horse, great mare | A horse goddess honoured across the Celtic world |
| Cerridwen | Keeper of the cauldron of wisdom | A Welsh enchantress and figure of poetic inspiration |
Brigid is the standout for real-world naming. It means exalted or high one, it doubles as the name of one of Ireland's most cherished saints, and its softer form, Bride, has a long history of its own. Aine, pronounced roughly "AWN-ya", is a lovely, compact choice meaning radiance, and it is far less familiar in English-speaking countries than it deserves to be. Rhiannon, sung about and written about for decades, has crossed over as a full given name and carries the regal meaning of great queen. Morrigan, Danu, Epona, and Cerridwen are darker and grander, better suited to parents who want something genuinely uncommon and are unafraid of a name with edges. You will find many of these on our girl names pages, each with pronunciation and background.
While Irish myth tends to dominate the conversation, Welsh legend is every bit as rich, and its names have a distinct flavour. The Mabinogion, a collection of medieval Welsh prose tales, gives us a cast of kings, queens, and enchanters whose stories loop through love, betrayal, and transformation. Rhiannon and Cerridwen, met above, belong to this world, and they are joined by figures like Branwen, whose tragic tale is one of the most moving in the whole collection, and Arawn, the noble lord of the Welsh Otherworld.
The Welsh tradition also gives us some wonderfully wearable shorter names. Nia, meaning brightness or radiance, has become a genuinely popular choice in Wales and beyond, helped along by its simplicity and warmth. Bran, whom we met among the Irish heroes, appears in Welsh legend too as Bran the Blessed, a giant king of enormous stature and generosity. Names like Dylan, meaning son of the sea, and Gwen, meaning white or blessed, also trace back to this mythic layer, though they have long since become everyday names in their own right. What unites the Welsh set is a musical quality and a fondness for meanings tied to nature, light, and the sea. To sit these beside the Irish material and see the full picture, the Gaelic baby names hub keeps the two traditions together in one place.
Welsh spelling looks daunting but follows steady rules. Rhiannon is "ree-AN-on", Branwen is "BRAN-wen", and Nia is simply "NEE-ah". When a name's look and its sound feel far apart, checking the pronunciation first, then deciding, saves a lot of second-guessing. Our advanced search lets you filter by origin so you can browse Welsh and Irish names side by side.
Beyond the gods and goddesses sits a third tier of characters: the lovers, poets, wanderers, and doomed royals whose human-scale stories give Celtic myth its emotional pull. Many of the most beautiful names come from exactly here, from the people caught up in the great tales rather than the deities presiding over them. Several of these figures move between the ordinary world and the Otherworld, the shimmering parallel realm that lies at the heart of the Celtic imagination.
| Name | Meaning | Their story |
|---|---|---|
| Deirdre | Sorrowful, or one who chatters | The tragic heroine of Ireland's most famous love story |
| Oisin | Little deer, young deer | Poet-warrior son of Finn who journeyed to the land of youth |
| Aengus | True vigour, one strength | A youthful god of love, poetry, and inspiration |
| Branwen | Blessed raven, white raven | A Welsh princess whose marriage ends in sorrow |
| Arawn | Uncertain; a Welsh royal name | The just and courteous king of the Welsh Otherworld |
Deirdre is the classic here, a name with real depth of feeling and a long history of use, though its melancholy meaning gives some parents pause. Oisin, pronounced "USH-een" or "oh-SHEEN", is a tender and increasingly popular Irish choice meaning young deer, and it belongs to one of the most poignant stories in all of myth, that of a hero who spends what feels like three years in the land of eternal youth only to find that three centuries have passed at home. Aengus is bright and youthful, tied to a god of love. Branwen carries the same raven imagery as Bran with a softer, more feminine finish. Arawn is a rarer, kingly Welsh option for the truly adventurous. These are names that reward a little storytelling when a child grows old enough to ask where their name came from.
Not every mythological name is built for daily life, and that is fine. Part of the fun is admiring the grand ones while choosing something a child can actually carry to school without a lifetime of spelling it out. The shortlist below gathers the Celtic myth names that translate most easily into the modern world: recognisable, straightforward to say, and warm rather than heavy.
| Name | Meaning | Best for |
|---|---|---|
| Finn | Fair, bright | A short, confident boy name that already feels at home |
| Brigid (Bride) | Exalted, high one | A girl name with saintly warmth and a soft nickname |
| Rhiannon | Great queen | A lyrical girl name with a strong, regal meaning |
| Nia | Brightness, radiance | A gentle, easy girl name that travels anywhere |
| Aine | Radiance | An uncommon girl name with a luminous meaning |
| Bram | Raven (from Bran) | A crisp, characterful boy name with literary charm |
These six strike the balance most parents are looking for. Finn is the safest crossover pick and pairs happily with almost any surname. Brigid gives a child both a dignified full name and the sweet short form Bride. Nia and Aine both mean brightness and radiance, making them a natural sibling match, while Rhiannon offers something a little longer and more musical. Bram, a trim relative of Bran, has a bookish appeal thanks to its literary associations and works beautifully as a standalone name or as a nickname for a longer one. If you would like to see how these compare on popularity and meaning against other choices, our boy names and girl names sections lay them out clearly.
Because so many Celtic myth names mean light or radiance, they harmonise without matching too obviously. Aine and Nia, or Finn and Brigid, make sibling sets that share a quiet thread of meaning while sounding entirely distinct.
The figures above are the headline acts, but Celtic naming runs far deeper than any single guide can capture. Beyond the gods and heroes lie hundreds of saints' names, place names, nature words, and old family names, each with its own meaning and music. If this tradition speaks to you, the best next step is to browse the wider pool and let a few more names catch your eye. Start with our Gaelic baby names hub, which brings the Irish and Welsh strands together, then follow your instincts.
From there you have a few useful paths. If a particular meaning moved you, whether it was light, raven, queen, or the sea, our names by meaning tool will surface every name that shares it. If you want to place Celtic names in a global context and see how neighbouring traditions handle similar ideas, the baby names by origin hub is the place to wander. And when you are ready to narrow things down by gender, sound, or popularity, the advanced search does the filtering for you. For more storytelling guides like this one, the blog collects them all in one place.
Are Celtic mythology names hard to spell or say? Some of the original forms look unfamiliar, but the wearable picks in this guide, such as Finn, Nia, Brigid, and Bram, are all simple to spell and pronounce in English. For the trickier ones, learning the sound first makes the decision much easier, and most settle into a single steady pronunciation.
Do I need Irish or Welsh heritage to use these names? Not at all. Mythological names belong to the stories they come from, and plenty of families choose them purely for their meaning and music. That said, if a name honours your own roots, that adds a lovely personal layer on top.
Which Celtic myth name is the most usable today? Finn for a boy and Brigid or Nia for a girl are the gentlest entry points. They are recognisable, easy to live with, and still carry the full weight of their ancient meanings.
Are these names only for boys or only for girls? Most sit clearly on one side, but the tradition is flexible. Bran and Finn read as boy names, while Rhiannon, Aine, and Brigid read as girl names. Browsing our girl names and boy names pages side by side is the quickest way to see where each one lands.
Celtic mythology offers something increasingly rare in a baby name: genuine depth. Behind each of these names stands a god, a queen, a warrior, or a wanderer, and behind each of those stands more than a thousand years of storytelling from Ireland and Wales. The grand names, the Dagdas and Cerridwens and Morrigans, are treasures to admire, while the wearable set, Finn, Brigid, Rhiannon, Nia, Aine, and Bram, gives a real child a name that is easy to carry yet impossible to exhaust. Whether you are drawn to the luminous meanings of light and radiance, the raven imagery of Bran and Branwen, or the regal weight of a name like Rhiannon, there is a Celtic name here waiting to be chosen. Begin your search on our Gaelic baby names hub, and let the old stories help you find the one that fits.
