Crocco is a lunar impact crater that is located on the far side of the Moon from the Earth.

The opposite half of the floor displays some irregularities, including the rim of a small crater that has been almost completely submerged by the lava flow.

This crater has a gap in the north rim, and forms a bay on the interior floor of Crocco.

A ridge runs from the western rim of this small crater to the southwest inner wall of Crocco.

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