Wilhelm is a lunar crater in the southern part of the Moon, to the west of the prominent Tycho crater. Portions of the ray material from Tycho lay across the rim and floor of Wilhelm crater. Attached to the southern rim is the Montanari crater, while Lagalla crater is attached to the southwest. To the north-northeast is Heinsius crater.

This crater formation is of the type termed a walled plain. It has a heavily eroded outer rim that is overlaid by several smaller craters. Among these are the 'Wilhelm A' and 'Wilhelm K' crater pair across the southwest rim, and 'Wilhelm B' just to the northwest along the western rim. 'Wilhelm C' is intruding into the north-northeast rim, and 'Wilhelm D' is attached to the northeast outer rim. There is an outward protrusion in the southern rim that extends to contact Montanari crater.

The interior floor of Wilhelm is relatively level, with a relatively rough area to the northeast. The remainder is flat and almost featureless except for a few tiny craterlets.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Wilhelm crater.
