Espin is a lunar impact 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. It is named after Thomas Henry Espinell Compton Espin, an amateur astronomer who was a vicar of Tow Law.

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.
