Cooper is a lunar impact crater that is located in the northern hemisphere on the far side of the Moon.
It lies to the east of the large walled plain D'Alembert, and west-southwest of the crater Chappell.
Multiple small craters lie across the rim and inner wall, leaving a ring-shaped formation of ridges in the lunar terrain.
The interior floor is slightly less rough than the surrounding surface, with a cluster of small craterlets near the northeast inner wall.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Cooper.
