Wichmann is a bowl-shaped lunar impact crater. It was named after German astronomer Moritz L. G. Wichmann.[1] It is located in the southern half of Oceanus Procellarum on a low plateau formed from a wrinkle ridge, Dorsa Ewing.

EponymMoritz L. G. Wichmann

There is a small mountain chain to the north that curves away to the west that is designated Wichmann R; this is most likely the rim of a worn crater that was buried by the lava flow forming the mare. Additional low mountains lie to the south of the plateau on which Wichmann is situated.
