Hopmann is a lunar impact crater that lies in the southern hemisphere on the Moon's far side.

The outer rim of this crater has undergone some wear due to impact erosion.

The interior floor is relatively level and has a lower albedo than the surrounding surface, giving it a slightly dark appearance.

There are some low ridges near the crater midpoint, and a double-ringed rim to the south-southeast of the center.

A tiny craterlet to the northwest of the midpoint is surrounded by a small skirt of higher albedo material, giving it the appearance of a white patch.
