The Man in the Moon is a figure resembling a human face, perceived in the full Moon in some cultures. The figure is composed of large dark areas (the lunar maria, or seas) on the Moon's surface. The figure's eyes are the Mare Imbrium and Mare Serenitatis, its nose is the Sinus Aestuum, and its open mouth is the Mare Nubium and Mare Cognitum.

Other cultures perceive the silhouette of a woman, a hare, or a buffalo in the full moon.
