Valier is a lunar impact crater that lies on the far side of the Moon.

To the north-northwest lies the larger Sharonov, to the south-southwest is Coriolis, and west of Valier is Dufay.

The inner walls of Valier are uneven slopes that are marked by several tiny craters.

The surviving interior floor is a relatively level surface with some tiny craters scattered about.

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