Brigit, Brigid or Bríg ('exalted one') is a goddess of pre-Christian Ireland. She appears in Irish mythology as a member of the Tuatha Dé Danann, the daughter of the Dagda and wife of Bres, with whom she had a son named Ruadán.

She is associated with the spring season, fertility, healing, poetry and smithcraft. Cormac's Glossary, written in the 10th century by Christian monks, says that Brigid was "the goddess whom poets adored" and that she had two sisters: Brigid the healer and Brigid the smith. This suggests she may have been a triple deity.

Brigid is considered the patroness of poetry, smithing, medicine, arts and crafts, cattle and other livestock, sacred wells, serpents (in Scotland) and the arrival of early spring. Pre-Christianization women would tend a sacred flame in her honor. Her festival day, Imbolc is traditionally a time for weather prognostication:

In her English retellings of Irish myth, Lady Augusta Gregory describes Brigit as "a woman of poetry, and poets worshipped her, for her sway was very great and very noble. And she was a woman of healing along with that, and a woman of smith's work, and it was she first made the whistle for calling one to another through the night."

She is the goddess of all things perceived to be of relatively high dimensions such as high-rising flames, highlands, hill-forts and upland areas; and of activities and states conceived as psychologically lofty and elevated, such as wisdom, excellence, perfection, high intelligence, poetic eloquence, craftsmanship (especially blacksmithing), healing ability, druidic knowledge and skill in warfare.

Brigid is an important figure for modern pagans, who emphasize her triple aspect. She is sometimes worshipped in conjunction with Cernunnos.
