Freud is a tiny lunar crater that lies on a plateau within the Oceanus Procellarum, in the northwest part of the Moon's near side. It is located a few kilometers to the west of the Vallis Schröteri, a large, sinuous valley that begins to the north of Herodotus crater, then meanders north, then northwest, and finally southwest, until it reaches the edge of the lunar mare.
