Aita (), also spelled Eita (), is an epithet of the Etruscan chthonic fire god à Âuri as god of the underworld, roughly equivalent to the Greek god Hades ().
Aita is a relatively late addition to the Etruscan pantheon, appearing in iconography and in Etruscan texts beginning in the 4th century BC, and is heavily influenced by his Greek counterpart, Hades. Aita is pictured in only a few instances in Etruscan tomb painting, such as in the Golini Tomb from Orvieto and the tomb of Orcus II from Tarquinia. In these tomb paintings, he is shown with his consort Persipnei (), also spelled Phersipnai (), the Etruscan equivalent of the Greek Persephone.
Although Aita is very rarely depicted, he may appear enthroned and sometimes wears a wolf cap, borrowing a key attribute from the earlier Etruscan underworld wolf deity, named Calu. Other examples of Aita in Etruscan art depict his abduction of Persipnei. Aside from tomb painting, Aita may be identified in a few examples in other media, including a 4th-century painted vase from Vulci, two 2nd-century alabaster ash urns from Volterra, and a red-figure 4th3rd century Oinochoe.
