Espin is a lunar crater that lies on the far side of the Moon, just beyond the northeastern limb. It lies to the west-southwest of the larger crater Seyfert, and northwest of Deutsch.

This is a worn formation with heavy damage along the northern rim. Several small craters lie along the northern edge, and a crater lies across the southern rim. The northern part of the interior floor is somewhat irregular, but it is more level to the south. A ray from the crater Giordano Bruno to the north-northwest reaches the western interior of Espin.

Satellite craters

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