Chernyshev is a lunar impact crater that is located in the northern part of the Moon's far side.

It lies to the northeast of the crater Chandler, and to the southeast of the walled plain D'Alembert.

The interior floor is more heavily impacted in the eastern half when compared to the west, although even the later region is not free of small impacts.

The floor is otherwise relatively level and lacks a central peak or significant ridges.

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