Denning is a lunar crater that is located on the far side of the Moon. It lies about midway between Levi-Civita crater to the south and Marconi crater to the north-northeast. About two crater diameters to the southeast is the huge Gagarin walled plain.

The rim of this worn crater is circular but somewhat irregular-edged. There is a low central rise at the mid-point consisting of at least two hills. Attached to the southwest outer rim is the larger satellite crater 'Denning R'. About one crater diameter the southeast of Denning is a bright patch of high albedo surface. This patch was most likely created by a small, relatively recent impact.

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 Denning crater.
