Cremona is a lunar crater that is located long the north-northwestern limb of the Moon. From the Earth this crater is viewed from the side, and the visibility is affected by libration effects. To be viewed in any detail, this crater must be seen or photographed from orbit. It is located midway between the crater Boole to the south-southeast and, on the far side of the Moon, the crater Lindblad.

This is a relatively old, worn crater that is overlaid by a number of smaller craters. The rim has been worn down and rounded by lesser impacts, leaving only a wide depression in the surface with somewhat irregular interior walls. Small craters lie across the north and northwestern rims, and the satellite crater Cremona L is laid across the southern rim. A band of tiny craterlets lies across the northeastern part of the rim, continuing part of a pattern of multiple craterlets that continue to the north.

The craters Cremona B and C form a double-crater pair in the northwestern part of the floor. The inner wall on the western side is unusually wide, forming a rough interior surface. The floor in the eastern half is more level, and contains the remnant of a central peak attached to the eastern rim of Cremona C.

Satellite craters

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 Cremona.
