Kircher is a lunar impact crater that is located in the south-southwestern part of the Moon, near the southern limb.

In this position the crater appears foreshortened when viewed from the Earth.

This crater is distinctive for an interior floor that is level and nearly featureless.

Attached to the outside of the western rim is a crater pair, with the larger of the two designated Kircher D. A small, cup-shaped crater lies on the narrow neck of ground between Kircher and Wilson.

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