Klaproth is an old lunar impact crater that lies in the rugged southern highlands of the Moon's near side.

The outer rim of Klaproth has been deeply eroded, incised, and reshaped by a long history of bombardment.

The remaining floor has been resurfaced by some material in the past, possibly fluidized ejecta or lava, leaving a level and nearly featureless surface that is marked only by a multitude of tiny craterlets.

The crater was named after Martin Heinrich Klaproth, the German chemist and discoverer of Uranium.

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