Obruchev is a disintegrating lunar crater that lies along the southern shore of Mare Ingenii, on the far side of the Moon. Less than three crater diameters to the south of Obruchev is Chrétien crater, and about the same distance to the southeast lies Oresme crater.
The outer rim of this crater has been heavily damaged and now forms an irregular, rugged ring about the interior. The crater partly overlays the satellite crater 'Obruchev M' to the south, and there are a pair of smaller craters along the western rim and inner wall. The interior of Obruchev has some uneven edges, but it is relatively level and featureless nearer the center.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Obruchev crater.
