Wegener is a lunar impact crater that is located in the Moon's northern hemisphere, about midway between the equator and the north pole.

The southwestern rim of Wegener intrudes slightly into the much larger walled plain Landau.

Wegener lies at the approximate margin of the Coulomb-Sarton Basin, a 530 km wide impact crater of Pre-Nectarian age.

The crater was named after the German geophysicist, polar researcher and meteorologist Alfred Wegener, originator of the theory of Plate tectonics.

[2] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Wegener.
