Diameter	137 km
Depth	Unknown
Colongitude	212° at sunrise
Eponym	Sergey Chaplygin

Chaplygin is a large lunar impact crater that lies on the far side of the Moon. It is located to the southeast of the huge Mendeleev walled plain, about mid-way between Schliemann crater to the northeast and Marconi crater to the southwest. In dimension, this crater is about the same size as Albategnius on the near side.

The rim of this crater is roughly circular, but with an uneven edge. The inner wall is terraced around much of the circumference, but this structure is somewhat disrupted along the southern side. The rim is only mildly eroded, with few craters around the edge — the exception being 'Chaplygin K' which is intruding into the inner wall along the southeast side. Within the walls is an interior plain that is level and smooth in comparison to the rugged terrain that surrounds the exterior of the crater. There is a central peak near the mid-point, and a few tiny craters lie scattered across the surface.

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 Chaplygin crater.
