The Morrígan ("phantom queen") is a figure from Celtic Mythology who appears to have been considered a goddess, although she is not explicitly referred to as such in the texts.

The Morrígan is a goddess of battle, strife, and sovereignty. She sometimes appears in the form of a crow, flying above the warriors, and in the Ulster cycle she also takes the form of an eel, a wolf and a cow. She is generally considered a war deity comparable with the Germanic Valkyries, although her association with a cow may also suggest a role connected with wealth and the land.
