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 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. The lack of prominent rays puts the age of this crater at about a billion years or more.

To the north of Timocharis crater 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 mid-point that is closest to Timocharis crater.

The following craters have been renamed by the IAU.
* Timocharis A — "See" Heinrich crater.
* Timocharis F — "See" Landsteiner crater.
* Timocharis K — "See" Pupin crater.
