Glaisher is a lunar impact crater that is located in the region of terrain that forms the southwest border of Mare Crisium. It lies to the southwest of the lava-flooded crater Yerkes, and west-northwest of the GreavesLick crater pair. It is surrounded by a ring of satellite craters of various dimensions, the larger companions generally being arranged to the south of Glaisher.

This crater is circular, with a bowl-shaped interior and a small floor at the midpoint. The crater has not been significantly worn by subsequent impacts. A merged, double-crater formation is attached to its southern rim, consisting of Glaisher E at the northwest end and Glaisher G to the southeast.

The crater was named after British meteorologist James Glaisher and its name was approved by the IAU in 1935.[1]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Glaisher.
