Sheepshanks is a small lunar impact crater located near the northern edge of Mare Frigoris.

Due south on the opposite shore is the prominent crater Aristoteles while to the north is C. Mayer.

About 30 kilometres (19 mi) to the southeast of the crater rim is the western end of the narrow rille named Rima Sheepshanks.

This cleft extends for a distance of about 200 kilometres (120 mi) across the surface of the mare, running to the east-northeast.

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