Ramsden is a lunar impact crater located on the western stretch of the Palus Epidemiarum. It was named after British instrument maker Jesse Ramsden. To the east-southeast is the crater Capuanus, and to the north lies Dunthorne. 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.
