Vilʹev is an eroded lunar impact crater that is located on the far side of the Moon.

Just to the northeast of Vilʹev is the small crater pair of van den Bos and Tamm.

Vilʹev is significantly eroded, and the outer rim now forms a somewhat irregular ring of ridges about the interior floor.

Near the center of the crater is a pair of smaller, cup-shaped impacts that are joined along their outer rims.

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