Theophrastus is a small lunar impact crater at the southern part of the Sinus Amoris, a bay at the northeast part of the Mare Tranquillitatis.

It was named after ancient Greek philosopher Theophrastus in 1973.

[2] It lies to the southeast of the lava-flooded crater Maraldi, and was designated Maraldi M until the IAU gave it its current name.

This is a circular crater, with inner walls that slope down to the midpoint and a rim that rises slightly above the surrounding lunar mare.

The crater has nearly the same low albedo as the nearby surface.
