Shayn is an eroded impact crater that lies on the Moon's far side. It lies to the north of Freundlich crater and northeast of Trumpler crater. To the west of Shayn is Nusl crater, and to the north-northeast lies Champollion crater.
This is an eroded crater formation that has undergone wear from subsequent impacts. Most of the rim has become rounded and the original sharp edges lost from a history of minor impacts. The southern inner wall, however, still displays some slumped, shelf-like structure. A pair of small impacts lie along the inner wall in the northeast part of the crater. The interior floor is pitted with small and tiny craterlets. The most notable of these is a small crater to the northwest of the mid-point.

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 Shayn crater.
