Sharp-Apollo crater is a small crater in Oceanus Procellarum on the Moon. The name of the crater was formally adopted by the IAU in 1973.

Apollo 12 astronauts Pete Conrad and Alan Bean landed the Lunar Module (LM) Intrepid northeast of Sharp-Apollo crater on November 19, 1969. The astronauts simply called it Sharp during the mission. To the east of Sharp is the larger Bench crater. More distant and to the northeast are Head and Surveyor craters.

The crater was described in the Apollo 12 Preliminary Science Report:Apollo 12 Preliminary Science Report, NASA Special Publi PDFcation 235, 1970. [https://ntrs.nasa.gov/api/citations/19700025955/downloads/19700025955.pdf PDF]

:Sharp Crater has a rim 0.66 m high that is composed of material with high albedo. This material has been splashed out radially around the crater and is softer than the normal regolith. A core tube driven into the rim of the crater penetrated the ejecta without difficulty. Samples collected near the center may show the youngest exposure ages. Sharp Crater appears to have just barely penetrated the regolith. A terrace near the crater floor is probably controlled by the subregolith bedrock at a depth of approximately 3 m.
