651 Antikleia is a main-belt asteroid discovered on 4 October 1907 by August Kopff at the Heidelberg-Königstuhl State Observatory.[1] It is named for Anticlea the mother of Odysseus.[9] The name may have been inspired by the asteroid's provisional designation 1907 AN.

Antikleia is a member of the dynamic Eos family of asteroids that most likely formed as the result of a collisional breakup of a parent body.[10]
