Maupertuis is the remnant of a lunar impact crater that is located in the northern part of the Moon's near side.

It lies in the stretch of rugged terrain north of Sinus Iridum, a bay in the northwestern corner of Mare Imbrium.

This is a crater that has been nearly obliterated by a history of impacts, leaving only a disintegrated remnant of the original rim.

The surviving outer rim is not especially circular, having been reshaped into a somewhat pentagonal outline.

The crater was named for the French mathematician and astronomer Pierre Louis Maupertuis (1698–1759).
