For the Egyptian goddess, see Neith.
In Irish mythology Neit (Néit, Nét, Neith) was a god of war. He was the husband of Nemain, and sometimes of Badb. Also grandfather of Balor, he was killed at the legendary Second Battle of Moytura. The name probably derives from the proto-Celtic *nei-t- meaning fighting or passion. A similarly named deity appears on two Celtiberian inscriptions, as a Romanized Mars Neto and as Neito. Neit is also described as the uncle of the Dagda, who gave him Ailech Neit (Neit's Stonehouse), which is elsewhere described as the grave of Aed, son of the Dagda.
