'''Jenner''' is a [[Moon|lunar]] [[crater]] that is located within the [[Mare Australe]]. It lies just past the southeastern limb, on the [[Far side (Moon)|far side]] of the [[Moon]], and can be viewed from the [[Earth]] during periods of favorable [[libration]] and lighting. Nearly attached to the eastern outer rim of Jenner crater is the larger, flooded [[Lamb (crater)|Lamb crater]].

This is a nearly circular crater with a sharp but somewhat irregular edge that has not been significantly eroded. There are some [[terrace]]s, particularly along the southwestern inner walls, and some slumping along the southeastern rim. The interior floor has been flooded by [[basalt]]ic-[[lava]], leaving a dark, level interior. There are no breaks in the exterior rim where the lava could have entered the crater, so it was presumably flooded from below. The floor is marked only by a few tiny craterlets. Surrounding the Jenner crater is a [[rampart]] of ''ejecta'' that extends for over a half crater diameter in some directions.
