Timocharis is a prominent lunar impact crater located on the Mare Imbrium. The closest crater of comparable dimensions is Lambert crater to the west. The smaller Feuillée and Beer paired craters lie to the east of Timocharis.

The rim of Timocharis crater has a somewhat polygonal outline, with an outer rampart that extends over 20 kilometers in all directions. The interior wall is slumped and sharply terraced. The center of the floor is occupied by a craterlet that lies on a slight rise. This impact has almost completely removed the original central peak. The crater has a minor ray system that extends for over 130 km.

To the north of Timocharis crater is a tiny crater chain named the Catena Timocharis.
