List of Celtic deities

The Celtic deities are known from a variety of sources such as written Celtic mythology, ancient places of worship, statues, engravings, religious objects, as well as place and personal names.

Celtic deities can belong to two categories: general and local. General deities were known by the Celts throughout large regions, and are the gods and goddesses called upon for protection, healing, luck, and honour. The local deities from Celtic nature worship were the spirits of a particular feature of the landscape, such as mountains, trees, or rivers, and thus were generally only known by the locals in the surrounding areas.

After Celtic lands became Christianised, there were attempts by Christian writers to euhemerize most of the pre-Christian deities. Some scholars have suggested that a few others, such as Brigit, may have become Saints in the Church. The Tuatha Dé Danann of Irish mythology, who were commonly interpreted as divinities or deified ancestors, were downgraded in Christian writing to fallen or ‘half-fallen’ angels, historical men, or demons; the latter has been the most common Christian view on most pagan deities. In many cases, traditions or practices, such as the reverence of holy wells, which often became baptismals, and most of which predate the coming of Christianity, that were considered redeemable were co-opted or reinterpreted as Christian.
