Diameter	49 km
Depth	Unknown
Colongitude	283° at sunrise
Eponym	Abraham G. Kästner

Kästner is a lunar crater that is located near the eastern limb of the Moon, to the southwest of the Mare Smythii. Just to the northwest of Kästner is the Gilbert walled plain. To the south is the prominent Ansgarius crater, and to the southwest lies La Pérouse crater.

This formation belongs to the category termed a walled plain. It has a worn, irregular outer wall that is overlaid by several small craters and there is a small break along the north-northeast. Along the northeastern rim is 'Kästner B', and to the southwest is the small 'Kästner E'. A shallow, unnamed crater is attached to the southern rim. The interior floor is relatively level and featureless, with only a few small craterlets and minor 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 Kästner crater.
