Petermann is a lunar crater that is located near the northern limb of the Moon, on the eastern hemisphere. It is located just to the north of the Cusanus crater, and the two are separated by a distance of about 10 kilometers. Due to its location, this crater appears significantly foreshortened when viewed from the Earth, and its visibility can be affected by libration.

Attached to the western rim of this crater is the large, heavily eroded crater 'Petermann R', which is much larger than Petermann although less prominent in appearance. The outer rim of Petermann crater is eroded, but retains some structure including traces of s. The inner wall varies in width around the perimeter, being wider to the south and southeast near Cusanus. The interior floor has been resurfaced, leaving a level plain that is marked only by a number of tiny craterlets and only a few low ridges near the sides.

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 Petermann crater.
