Ramsay is a lunar impact crater that is located on the Moon's far side. It lies to the south-southwest of the larger crater Jules Verne, and is nearly in contact with the satellite crater Jules Verne P along the northern outer rim. To the southeast of Ramsay is the crater Koch, and to the west-southwest lies the overlapping pair of Roche and Pauli.

This is a worn crater, although the rim retains a generally circular character and is marked only by tiny craterlets (except for a notch in the south-southeast). The interior floor is relatively featureless, with a low central rise near the midpoint.

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 Ramsay.
