Jeans is a lunar crater along the southeastern limb of the Moon. The majority of this formation lies on the far side with respect to the Earth, but favorable librations can bring the entire crater into view. Despite this, however, this crater is viewed from the side from Earth, limiting the amount of detail that can be observed.

This crater is located nearly midway between the much larger walled plain Lyot on the near side and the crater Chamberlin on the far side. It has a heavily worn and rounded outer rim, and several impacts lie along the southern and southeastern edge and inner wall. The most prominent of these intersecting craters are Jeans G across the eastern rim. The interior floor of Jeans has been resurfaced by basaltic lava, leaving a dark level surface marked only by a few tiny craterlets.

Satellite craters[edit]

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