Lamb is a lunar crater that lies beyond the southeastern limb on the Moon's far side. It is located in an irregular lunar mare region named Mare Australe, just to the east of the Jenner crater.

This crater has a slender inner wall and an interior floor that has been resurfaced by basaltic-lava. The rim is somewhat worn and irregular, but retains a generally circular shape and is not overlaid by any smaller craters of significance. The interior floor is marked only by a multitude of tiny craterlets, and a small, unnamed crater in the south-southeastern section.

The exterior of the crater consists of the outer rampart and sections of rough terrain. This in turn is nearly enclosed by lava-flooded sections of the surface belonging to the Mare Australe. To the east of Lamb crater is 'Lamb G', a somewhat smaller, lava-flooded formation.
