Gregory is a lunar crater on the far side of the Moon. It is located to the southeast of the crater Ibn Firnas, and north-northeast of Bečvář. About one crater diameter to the north is the smaller Morozov.

This is a worn and eroded crater formation. The northern rim is degraded due to impacts. Attached to the exterior of the southwest is Gregory Q, a satellite crater about the same size as Gregory. Within the interior is the remains of a small crater rim along the northwestern inner wall.

To the east of Gregory and leading away to the southeast is a crater chain designated Catena Gregory.

Satellite craters[edit]

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