Stefan is a lunar crater on the far side of the Moon, just beyond the northwestern limb. Attached to the western rim is the slightly smaller Wegener crater, and located close to the eastern rim is Rynin crater.

As with many craters of this size on the Moon, the outer rim has been worn by impact erosion and the edge and inner wall are generally pitted with small craterlets. The southern edge of the rim in particular has been damaged by impacts, and is overlaid by the satellite crater 'Stefan L'. This bowl-shaped crater lies at the center of a small ray system, which is indicative of a relatively young impact.

The interior floor of Stefan is a generally level surface that is marked by several impacts. The most notable is a ring-shaped crater rim projecting up through the southern half of the floor. Near the mid-point is a low hill, possibly the buried remnant of a central peak.

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 Stefan crater.
