Cuvier is a lunar impact crater on the southern part of the Moon's near side.

It is attached to the east-southeast rim of the unusually shaped formation Heraclitus.

The rim of this crater has been worn and eroded by subsequent impacts, leaving an outer wall that has been rounded and diminished in prominence.

This surface does not possess the low albedo characteristic of the lunar mare, and it matches the hue of the surrounding terrain.

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