Celtic deities are the gods and goddesses of the Celtic-speaking peoples of ancient Europe, from Gaul (roughly modern France) and Britain to Ireland and Wales. There was never one tidy Celtic pantheon: the Gaulish and British gods are known mostly from Roman-era inscriptions and Roman writers, and the Irish and Welsh ones from medieval manuscripts written centuries after Christianity arrived.
The Celtic pantheon is rich with gods and goddesses who embody the forces of nature, life, death, and the human experience. These deities, revered by the ancient Celts, represent everything from love, beauty, and fertility to war, chaos, and the mysteries of the natural world. Each carries unique stories, powers, and symbols that highlight the profound connection between the divine and everyday life.
From the fierce Morrígan and the wise Dagda to the nurturing Danu and the enchanting Aengus, these figures illustrate the Celts’ deep spiritual connection to the world around them. This guide explores the key Celtic deities, their domains, and their lasting impact on mythology and culture.
Those four are all Irish, and they only scratch the surface. For the Tuatha Dé Danann in depth, head to our guide to Irish Celtic gods and goddesses. This page takes the wider view, with Gaulish, British and Welsh deities sorted by domain alongside the Irish ones.
Celtic deities at a glance

Here is the whole pantheon on one page, sorted by domain and by where each deity comes from:
Where Do We Know the Celtic Deities From?
The Celts didn’t write their myths down themselves, so everything we know comes second-hand. That matters: every “fact” about a Celtic god has a source behind it, and the sources don’t always agree.
- Gaul and Britain: Julius Caesar described the Gaulish gods in the 50s BC using Roman names, with Mercury the most honoured, “inventor of all the arts”. The poet Lucan, writing in the 1st century AD, named three Gaulish gods outright: Teutates, Esus and Taranis. Hundreds more names survive on altars and inscriptions, often paired with a Roman god (Sulis Minerva, Mars Camulos).
- Ireland: the Irish gods survive in medieval manuscripts such as Lebor Gabála Érenn (the Book of Invasions) and Cath Maige Tuired (the Second Battle of Moytura), written down by Christian scribes long after Ireland converted. There the old gods appear as the Tuatha Dé Danann, a supernatural people rather than gods as such.
- Wales: the Four Branches of the Mabinogi, written down in the Middle Ages, keep figures such as Rhiannon, Lleu Llaw Gyffes and Manawydan, who are widely thought to be old gods in human form.
Fair warning, then: a lot of what you’ll read online about Celtic gods (the neat job titles, the exact festival roles) is modern. We flag it below where the evidence is thin, and there’s a short summary of ancient Celtic religion if you want the scholarly overview. If you’re fuzzy on who counts as Celtic in the first place, our explainer on the difference between Celtic and Gaelic sorts out the terms.
The Supreme Celtic Deities
The supreme deities of Celtic mythology, Dagda and Danu, stand as central figures of power, wisdom, and creation.
Goddess Danu, the great mother goddess, is the matriarch of the Tuatha Dé Danann, embodying fertility, abundance, and the nurturing forces of nature. She is associated with rivers and flowing waters, symbolizing life’s continuity and the unyielding power of the natural world. Dagda Mor, known as the “Good God,” is a father figure and protector, revered for his immense strength, boundless wisdom, and mastery of magic. As a god of fertility, life, and abundance, he wields the cauldron of plenty and the club that can both take and restore life.
One caveat on Danu: no myths about her survive in the medieval Irish texts, and the name “Danu” itself is a modern reconstruction from the “Danann” in Tuatha Dé Danann. She may be the same figure as Anu, whom a medieval Irish glossary calls mother of the gods. In Wales, Dôn, mother of a whole family of gods in the Mabinogi, is often compared with her.
Together, Dagda and Danu represent the balance of creation and sustenance, reflecting the interconnectedness of the natural and divine in Celtic belief. They are the cornerstone of Celtic mythology, revered as the ultimate sources of life, prosperity, and protection.
Outside Ireland, the closest thing to a sky god is Taranis, the Gaulish “thunderer”, often linked to the wheel symbol and matched by the Romans with Jupiter. Lucan pairs him with Teutates (“he of the tribe”) and Esus (“lord”), and Caesar says the Gauls claimed descent from a god he compared with the Roman Dis Pater. Nobody knows for sure how these Gaulish gods ranked against each other.
The Tuatha Dé Danann and Its Leaders
The Tuatha Dé Danann, the legendary people of the goddess Danu, were central figures in Celtic mythology, known for their wisdom, magical abilities, and strong leadership. Among their leaders were figures of immense power and influence who guided their people through triumph and turmoil.
King Nuada, the first king of the Tuatha Dé Danann, was revered as a symbol of strength and justice, famed for his magical silver hand that restored his ability to rule after injury. Nemain, a war goddess linked to chaos and battle, was a vital force in protecting the Tuatha Dé Danann, embodying the ferocity needed to defend their lands. Bodb Derg, another prominent leader, was celebrated for his wisdom and fairness, chosen as king after the Tuatha Dé Danann retreated to the otherworld. Together, these leaders and deities shaped the destiny of the Tuatha Dé Danann, ensuring their enduring legacy in Celtic lore.
Celtic Deities of War, Battle, and Death
The Celtic deities of war, death, chaos, and battle reflect the fierce and transformative forces of conflict, each embodying different aspects of these powerful themes. The Morrígan, a triadic goddess usually grouped with her sisters Badb and Macha (with Nemain or Anann taking a place in some versions), represents the sovereignty of the land and the fate of warriors. Macha is tied to both battle and the fertility of the land, embodying the duality of creation and destruction.
Nemain, the goddess of panic and frenzy, spreads confusion and terror among enemies, turning the tide of battle through chaos. Badb, often appearing as a crow, symbolizes prophecy and carnage, her presence a harbinger of death. Donn, the Lord of the Dead, oversees the passage of souls to the otherworld, linking the end of life to its cyclical renewal. Together, these deities portray the Celts’ reverence for the chaotic, yet sacred, nature of war and death as essential forces in the balance of existence.
Britain and Gaul had war gods of their own, known mostly from inscriptions. Camulos is paired with Mars on altars from Reims in France to the Antonine Wall in Scotland, and Colchester’s Roman name, Camulodunum, may mean “fort of Camulos”. Andraste is known from a single story: the Roman historian Cassius Dio says Boudica called on her during the revolt against Rome in AD 60 or 61.
Celtic Deities of Nature
The Celtic deities of nature and the natural elements embody the profound connection between the divine and the environment, reflecting the Celts’ deep respect for the land, waters, and skies. Boann, the goddess of the River Boyne, symbolizes the power of flowing water to shape and sustain life, her story illustrating the spiritual significance of Ireland’s rivers. Áine, a goddess of summer and fertility, is associated with the sun’s vitality and the abundance of the natural world, often linked to the cycles of growth and renewal.
Ériu, one of the three sovereignty goddesses of Ireland, personifies the land itself, her name becoming synonymous with Ireland and representing its spirit and sovereignty. Manannán mac Lir, the sea god, embodies the mystery and vastness of the ocean, guiding souls to the otherworld and controlling the mists that veil its secrets. Together, these deities represent the balance and power inherent in the natural world, central to Celtic mythology.
Across the water, the best-known nature god is Cernunnos, the horned Celtic god of Gaul. His name appears on the Pillar of the Boatmen in Paris (though even that reading is disputed), and he is probably the antlered figure on the Gundestrup Cauldron found in Denmark. Most of what gets written about him beyond that is educated guesswork.
Epona, the Celtic horse goddess, was one of the few Celtic deities the Romans never swapped for a god of their own. Her images turn up from Gaul to the Danube, and even at the barracks of the emperor’s horse guards in Rome. In Britain, Sulis ruled the hot springs at Bath, where about 130 curse tablets, mostly addressed to her, have been pulled from the sacred spring. Most of them complain about theft, from small sums of money to clothes taken at the Roman baths at Aquae Sulis, which tells you some things never change.
Celtic Deities of Knowledge and the Arts
The Celtic deities of knowledge, arts, craftsmanship, and learning represent the intellectual and creative brilliance of the ancient Celts, blending wisdom, skill, and innovation. Dian Cecht, the god of healing and medicine, was revered for his profound knowledge of restorative arts, crafting miraculous cures and symbolizing the link between wisdom and well-being. Ogma, the god of learning, is credited with creating the Ogham script, embodying the power of language and its role in preserving knowledge and culture.
Goibniu, the divine smith, was a master craftsman whose creations included unbreakable weapons and the ale of immortality, demonstrating the artistry and magic of skilled labor. Lugh, the multi-talented god of arts and mastery, excelled in nearly every craft, earning him the title of Samildánach, or “Master of All Skills.” Together, these deities highlight the Celtic appreciation for knowledge and creativity as sacred forces that enrich and sustain life.
Lugh’s Gaulish counterpart, Lugus, gave his name to Lugdunum (modern Lyon), and many scholars think he is the god Caesar called the Gaulish Mercury, “inventor of all the arts”. Ogmios, a Gaulish god of eloquence, was described by the Greek writer Lucian as an old man leading a crowd by chains running from his tongue to their ears, and he is often linked with Ogma. Belenus, a god of light and healing in southern Gaul and northern Italy, was matched with Apollo.
Ireland’s Brigid belongs here too. A 9th-century Irish glossary calls her a goddess of poets, with two sisters of the same name linked to healing and smithcraft, and her name is related to Brigantia, a goddess of northern Britain. Her feast, Imbolc on 1 February, is one of the ancient pagan Celtic holidays, though how much of the goddess survives in Saint Brigid is still argued over.
Celtic Deities of Love
The Celtic deities of love, beauty, and fertility embody the joys of passion, romance, and the cycles of renewal that sustain life. Among them, Aengus, the god of love, poetry, and youthful vitality, is a central figure. Known as the “Young Son” or the “Mac Óg,” Aengus is often depicted as charming and playful. In one medieval story his kisses take the form of birds, and later Scottish folklore gives him a golden harp whose music draws young lovers after him.
Another prominent figure is Clíodhna, the goddess of beauty and the otherworld, who is associated with enchantment and love. She is said to have a voice as captivating as her appearance and is often linked to the tides, symbolizing the ever-changing nature of love. Together, these deities reflect the Celts’ reverence for the transformative power of love and its ability to inspire, heal, and connect both individuals and communities.
Wales has Rhiannon, the otherworld woman on the white horse in the Mabinogi, who chooses Pwyll as her husband over an unwanted suitor. Many scholars connect her with Epona and with Macha, which makes her as much a goddess of horses and sovereignty as of love. Gaul and Britain have no clear love deity in the surviving evidence.

Celtic Deities FAQ
What are Celtic deities?
Celtic deities are the gods and goddesses worshipped by the Celtic-speaking peoples of ancient Europe, including the Gauls, the Britons and the Irish. They include sky and tribal gods like Taranis and Teutates, war goddesses like the Morrígan, and local spirits of rivers and springs, such as Boann and Sulis.
How many Celtic deities were there?
There is no fixed number. Over 400 deity names are recorded in Gaul alone, and at least 300 of them appear only once, usually on a single altar or inscription. Add the Irish and Welsh figures from medieval texts and the total runs well into the hundreds, most of them local gods.
Who was the most powerful Celtic god?
It depends where you look. In Irish tradition the Dagda, the “Good God”, is the great father figure of the Tuatha Dé Danann. In Gaul, Julius Caesar said the god the Romans called Mercury was the most honoured, and many scholars think that was Lugus.
Are Celtic deities the same as Irish gods?
Not quite. The Irish gods are one branch of the Celtic deities, alongside the gods of Gaul, Britain and Wales. Some are clearly related, like Lugh and Lugus, but many Gaulish and British gods have no Irish counterpart, and the Irish stories were only written down in the Middle Ages.
Who is the Celtic goddess of love?
There isn’t one clear Celtic goddess of love. Ireland has Aengus, a god of love and youth, and Clíodhna, an otherworld queen linked to beauty. In Wales, Rhiannon’s story is a love story, but she is usually seen as a goddess of horses and sovereignty.
