Celtic Gods and Goddesses of Ireland: Names, Domains and Places

Article Summary

What this article covers: The Celtic gods and goddesses of Ireland, listed in full with their domains, pronunciation and the places their stories are set, plus the Gaulish and British deities people usually mean when they search for Celtic gods.

Who this is for: Anyone looking up which god rules which domain, readers after a name for writing or research, and travellers planning a trip around Ireland’s mythological sites.

Key takeaway: The Celtic gods were never one pantheon. Ireland’s gods, the Tuatha Dé Danann, are the best documented because Irish monks wrote the stories down, while the Gaulish and British gods survive mostly as names on altar stones.

Expert insight:

The first time I went into Oweynagat at Rathcroghan I had to crawl, and the entrance is a stone lintel with ogham cut into it. That is the Morrígan’s cave and there is no ticket office. Half of Irish mythology is like that, sitting in a field with a farmer’s gate across it.

Ciaran Connolly, Founder of ConnollyCove

Quick facts:

• Tuatha Dé Danann means “the people of the goddess Danu”, and they are the principal divine race in Irish myth
• Ireland has no god of thunder, no trickster god and no clear god of the sun, which is where most online lists start inventing
• Cernunnos, the antlered figure most people picture as a Celtic god, is Gaulish and does not appear in Irish sources at all

Most people arrive here with one of two questions. Either which god rules a particular thing, or what a particular name means.

Both are answered below, and ConnollyCove has put the directory of Celtic gods early so you do not have to read a history to find one name. What follows it is the detail. Who the chief figures are, how they relate to each other, and which of the Celtic gods you have read about are Irish and which are not.

One thing worth knowing before you start. The Celtic gods were not organised like the Greek or Norse pantheons. Ireland, Gaul, Britain and Wales each had their own. They overlap in places and contradict each other in others. The Irish material survives best because monks wrote it down between the seventh and twelfth centuries. ConnollyCove covers Irish heritage, so Ireland gets the most space here, and the others get a section of their own.

Which Celtic God Rules What?

The most common way people look up the Celtic gods is by domain, so here are the direct answers. Where Ireland genuinely has no equivalent, that is said rather than filled in, because a lot of what circulates online is invented to complete the set.

War. The Morrígan, usually as a triad with Badb and Macha, sometimes with Nemain instead. She does not fight so much as decide outcomes and forecast deaths. Our page on the Morrígan covers the triad in detail.

Nature, forests and animals. Cernunnos, the antlered god, and he is Gaulish rather than Irish. Ireland’s closest figure is Flidais, associated with deer and wild animals. See our guide to Cernunnos for the Gaulish material.

The sea. Manannán mac Lir, who crosses between the sea and the Otherworld, and Lir before him. ConnollyCove has a full page on Manannán mac Lir.

The dead. Donn, who gathers the dead at Tech Duinn off the Kerry coast. He guides rather than rules, and Irish tradition has no god of death in the Greek sense.

Healing. Dian Cécht and his daughter Airmid, whose herb lore appears in early Irish medical texts. Brigid also holds healing alongside poetry and smithcraft.

Poetry and eloquence. Brigid, and Ogma, who is credited with inventing the ogham script.

The harvest. Lugh, whose festival Lughnasadh marks the start of it in August.

Winter. The Cailleach, the hag who makes the cold season and hands the year back to Brigid at Imbolc.

Love. Áine for summer love, Aengus for young love, and Clíodhna in Munster tradition.

Rivers and water. Boann for the Boyne and Sinann for the Shannon. Both drowned approaching a forbidden well of wisdom, and both rivers carry their names.

Wisdom and knowledge. No single god. Wisdom in Irish myth attaches to the Well of Segais and the salmon that eat its hazelnuts rather than to a deity.

Smithing and craft. Goibniu the smith, Luchtaine the carpenter and Creidhne the metalworker, who together armed the Tuatha Dé Danann at Mag Tuired.

Thunder and storms. Taranis, and again Gaulish. Ireland has no thunder god, which is the single most common invention on lists of Celtic gods.

The sun. No Irish sun god. Lugh is often given the role and the association is modern. Belenus in Gaul is the closer fit.

Trickery. No Irish trickster deity. The púca is folklore rather than a god, and belongs with the legendary creatures of Celtic mythology instead.

The Chief Gods of the Irish Pantheon

Four of the Celtic gods carry most of the narrative: a father, a polymath, a deposed king and a lord of the sea.

The Dagda

The Dagda, meaning the Good God, led the Tuatha Dé Danann and stood for abundance, wisdom and force in equal measure. His club killed with one end and revived with the other. His cauldron never emptied. His harp could turn the seasons and move an army from grief to laughter and back.

He is tied to the Boyne Valley, where his dwelling was said to lie beneath the great mound before he handed it to his son Aengus.

Lugh Lámhfhada

Lugh, called Lámhfhada for his long reach, is the one who is good at everything. When he arrived at Tara he was refused entry until he pointed out that no one else present could do all his crafts at once.

He led the Tuatha Dé Danann against the Fomorians at the second Battle of Mag Tuired and killed his own grandfather Balor with a sling stone. His parentage is the point of him: a Tuatha Dé Danann father and a Fomorian mother make him the bridge between the two sides.

Nuada Airgetlám

Nuada was the first king of the Tuatha Dé Danann and lost his arm fighting the Fir Bolg. Irish kingship required physical wholeness, so he stepped down, and Bres took the throne and ruled badly.

Dian Cécht fitted Nuada with a working silver arm, giving him the name Airgetlám, and he took the kingship back. His sword was one of the four treasures.

Manannán mac Lir

Manannán rules the sea and moves freely into the Otherworld, sailing a boat that needs no oars and wearing a cloak that raises mist to hide an island. He acts as guide and protector to the rest of the pantheon more often than he acts for himself, and he is strongly tied to the Isle of Man.

The Goddesses and the Sovereignty of the Land

The Celtic goddesses of Ireland are not consorts. Many of them are the land, and a king’s right to rule depended on a symbolic marriage to a sovereignty goddess who embodied the territory. That idea has no real parallel in Greek or Norse myth, and it is the most distinctive thing about the Celtic gods and goddesses of Ireland.

Danu

The Tuatha Dé Danann are named for her and she barely appears. No story survives in which Danu acts. She is a mother figure reconstructed largely from the group’s name and from river names across Europe, and the honest position is that we know almost nothing about her.

The Morrígan, Badb, Macha and Nemain

The Morrígan is a goddess of war, fate and sovereignty, usually understood as a triad. Which three varies by source: Badb, Macha and Anand in some, Badb, Macha and Nemain in others.

She appears as a crow over battlefields in the Táin Bó Cúailnge, and as the washer at the ford, seen scrubbing the armour of a man about to die. Macha carries her own cycle at Emain Macha in Armagh, where she was forced to race against horses while pregnant and cursed the men of Ulster as she died.

Brigid

Brigid holds healing, smithcraft and poetry, an unusual combination that suggests an older and broader figure. A flame kept in her honour at Kildare was said to have burned for centuries.

Her festival Imbolc marks the first stirring of spring, and her identity merged so completely with Saint Brigid that the two have never been fully separated. Imbolc is now covered in our guide to the four Celtic festivals.

Ériu, Banba and Fódla

Three sisters, each of whom asked the arriving Milesians to name the island after her. Ériu won, and Éire is her name. Banba and Fódla survive as poetic names for Ireland. They are the clearest example of the sovereignty goddess: the land itself, negotiating with whoever intends to rule it.

Áine, Boann and Clíodhna

Áine is tied to Cnoc Áine in County Limerick, where midsummer fire rituals were recorded into the twentieth century. Boann gave her name to the Boyne after approaching the Well of Segais against warning, and the river is the water that pursued her. Clíodhna belongs to the Cork coast, where a wave at Glandore still carries her name.

The Cailleach

The hag of winter, who makes the cold and sleeps through summer. She is the counterweight to Brigid and between them they hold the year. Our guide to the Cailleach covers her seasonal role and the mountains she is attached to.

The Celtic Gods Family Tree

The relationships between the Celtic gods are inconsistent between sources, so treat this as the commonest version rather than a fixed genealogy.

Danu is named as mother of the Tuatha Dé Danann, though no text describes her doing anything.

The Dagda is the father figure of the group. His children include Aengus, born of his affair with Boann, Brigid, and Bodb Derg, who succeeded him as king of the sídhe.

Lugh sits outside that line. His father was Cian, son of Dian Cécht, and his mother was Ethniu, daughter of the Fomorian Balor. That makes Lugh the grandson of the enemy he kills.

The Morrígan is variously given as the Dagda’s consort. They meet at the ford of the Unshin before the second Battle of Mag Tuired, and she gives him the outcome.

Manannán mac Lir is son of Lir, and generally treated as belonging to an older layer than the rest.

The Fomorians are not a separate pantheon so much as the other half of the same one. Bres, briefly king of the Tuatha Dé Danann, had a Fomorian father and a Tuatha Dé Danann mother, exactly mirroring Lugh.

Celtic Gods Beyond Ireland: Gaul, Britain and Wales

If you searched for Celtic gods and were expecting Cernunnos, this is the section you want. Ireland’s are the best recorded, and they are where ConnollyCove’s own work sits. They are not the only ones, and several of the most recognisable Celtic gods are not Irish at all.

Cernunnos is the antlered figure on the Gundestrup cauldron, associated with animals, forests and abundance. He is Gaulish, he appears in no Irish source, and he is the single most misattributed figure in Celtic myth.

Taranis held thunder, Toutatis the protection of the tribe, and Esus is a woodcutter figure whose function is unclear. Roman writers grouped these three and reported human sacrifice attached to them, which is a hostile source and should be read as such.

Belenus was a god of light and healing, and his name may sit behind Bealtaine. Epona, the horse goddess, is the one Gaulish deity the Roman army adopted wholesale, and she connects to the Irish Macha and the Welsh Rhiannon.

Welsh tradition, recorded in the Mabinogi, gives Rhiannon and Arawn of the Otherworld. It also gives Lleu Llaw Gyffes, clearly related to Lugh, and Manawydan fab Llŷr, who is Manannán under a Welsh name.

Most of the Gaulish Celtic gods survive only as names carved on altar stones by Roman-era soldiers and traders. There are no Gaulish myths, because nothing was written down. For the Irish material, the medieval texts are translated and freely readable at CELT, the Corpus of Electronic Texts at University College Cork.

Where to Visit These Myths Today

You do not need to imagine these settings. Most are real, open and walkable, and ConnollyCove has visited all six.

Brú na Bóinne, County Meath. The passage tomb complex including Newgrange, tied to the Dagda, Boann and Aengus. Guided tour from the visitor centre, and it needs booking.

Hill of Tara, County Meath. Seat of the Tuatha Dé Danann kings and later the High Kings. The Lia Fáil, one of the four treasures, still stands on the summit. Free and open.

Hill of Uisneach, County Westmeath. Traditionally the sacred centre of Ireland and the site tied to Ériu. Guided tours in season.

Rathcroghan, County Roscommon. Includes Oweynagat, described in medieval sources as an entrance to the Otherworld and associated with the Morrígan. Access through the visitor centre.

Emain Macha, County Armagh. Navan Fort, the seat of the Ulster Cycle and Macha’s site.

Loughcrew, County Meath. Cairn T and the hill known as the Hag’s Chair, attached to the Cailleach.

These sit alongside the wider set covered in ConnollyCove’s guide to prehistoric sites in Ireland.

The carvings you will see on them are explained in our guide to Celtic symbols.

The Celtic Gods in Modern Ireland

The Celtic gods never quite left Ireland. Samhain, which became Halloween, marked the point when the divide between this world and the sídhe was thought to thin. Imbolc, Brigid’s festival, became an Irish public holiday in 2023.

Farmers still leave certain hawthorns standing in the middle of ploughed fields, which is the reason our guide to fairy trees exists at all. The belief behind it is that the Tuatha Dé Danann went into the mounds rather than away.

The wider religious context is covered in ConnollyCove’s guide to Irish paganism.

Our account of the druids covers the people who mediated between the Celtic gods and everyone else.

The Tuatha Dé Danann page goes further into the arrival and defeat of the Celtic gods of Ireland.

If you take one thing from this, take the sovereignty idea. Ériu, Banba and Fódla negotiated with the incoming Milesians for the right to name the island. That tells you more about how the Celtic gods worked than any list of powers does. The land was a person you had to come to terms with.

Start at Uisneach or Rathcroghan if you want to see the Celtic gods rather than read about them. ConnollyCove has filmed at both.
