Geiger is a lunar crater on the far side of the Moon. It lies to the southwest of the much larger Keeler walled-plain, and slightly further to the northeast of the huge Gagarin walled-plain. To the south is the Cyrano crater.

This is a not-quite symmetrical crater formation with small outward bulges along the north and northeast. The rim to the southeast is less well-formed than elsewhere. The northern inner wall is more extensive than elsewhere, slumping across about one-third the inner floor. The interior is otherwise relatively level and is marked by a few tiny craterlets.

Satellite craters

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 Geiger crater.
