Cassegrain is a lunar impact crater that is located on the far side of the Moon, beyond the southeastern limb. It lies to the southeast of the larger Lebedev crater, and to the northeast of the comparably-sized Priestley crater.
The interior of this crater has a relatively dark-hued floor, a feature it has in common with other craters to the west and northwest that form part of the Mare Australe. The floor is level and mostly featureless, except for some deposits in the northwest corner. The rim is more heavily worn in the northwest corner than elsewhere, and the remaining inner wall displays a slumped shelf below the rim.

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 Cassegrain crater.
