In Irish mythology, Anann (Anu, Ana, Anand) was a goddess. ‘Anann’ is identified as the personal name of the Morrígan in many MSS of Lebor Gabála Érenn. With Badb and Macha, she is sometimes part of a triple goddess or a triad of war goddesses. As such, she may be a Celtic personification of death, and is depicted as predicting death in battle. As a goddess of cattle, she is responsible for culling the weak. She is therefore often referred to as "Gentle Annie", in an effort to avoid offense, a tactic similar to referring to the fairies as "The Good People".

She may be identical with Danu or Aine. She has particular associations with Munster: the twin hills known as the Paps of Anu (Dá Chích Anann ot the breasts of Anu), near Killarney, County Kerry are said to have been named after her. She was a goddess of fertility, cattle, and prosperity, and was known for comforting and teaching the dying. Fires were lit for her during Midsummer.
