Bruce is a small lunar impact crater located in the Sinus Medii. It lies to the west-northwest of the irregular crater Rhaeticus, and is about 33 km to the west of the even smaller Blagg.
This feature is circular and cup-shaped, with no notable impacts overlaying the rim or interior. The interior has a generally higher albedo than the surrounding terrain, but there is a band of darker material cross the midpoint of the crater from west to east. It is surrounded by lunar mare, with a few tiny craterlets in the surface to the east.
Less than forty kilometres to the south-southeast is the original point of the selenographic coordinate system. From the floor of this crater the Earth always appears at the zenith. Both the Surveyor 4 and Surveyor 6 probes landed about 50 km to the west-southwest of Bruce.
