Ramsden is a lunar impact crater located on the western stretch of the Palus Epidemiarum. To the east-southeast is Capuanus crater, and to the north lies Dunthorne crater.
The floor of the crater has been flooded with lava, and contains several small impact craters. The rim is somewhat oval and irregular in outline, with depressions at the north and south walls. It has a slight rampart, but lacks terraces, a central peak, or a ray system.
The crater lies directly across a rille system named the Rimae Ramsden. These span an area 130 kilometers across, sprawling over the western Palus Epidemiarum. A branch reaches northwest to the Mare Nubium, passing between the Campanus and Mercator 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 Ramsden crater.
