Charlier is a lunar impact crater located on the far side of the Moon.

To its south-southeast lies the larger crater Kovalevskaya, while Perrine is situated to the northeast.

The western rim, in particular, is overlaid by a merged cluster of multiple small impacts.

However, two patches of the interior remain relatively undisturbed by notable impacts—one near the northern part of the floor and another in the southwestern region.

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