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

The rim of Timocharis 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 may have a minor ray system that extends for over 130 km (81 mi). The lack of prominent rays puts the age of this crater at about a billion years or more.

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

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