Crater characteristics
Coordinates	22.6° S, 78.3° E
Diameter	49 km
Depth	3.4 km
Colongitude	79° at sunrise
Eponym	Lorentz Eichstadt

Eichstadt is a lunar impact crater that is located in the eastern section of the Montes Cordillera range that encircles the Mare Orientale impact basin. It lies toward the southwestern limb of the Moon, and so appears oblong when viewed from the Earth due to foreshortening. A couple of hundred kilometers to the east of Eichstadt is the Darwin walled plain.

The rim of this crater is well-defined and forms a somewhat uneven circle. There are slight outward bulges in the perimeter to the south-southeast, southwest, and to the north. There are some terraces along the inner wall and the top edge is slumped. In the central part of the interior floor is a cluster of low, rugged ridges.

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 Eichstadt crater.
