Saenger is an ancient lunar impact crater that lies on the far side of the Moon, just beyond the eastern limb. It was named after Austrian rocketry scientist Eugen Sänger.[1] To the west-northwest is the crater Erro, and due north lies Moiseev. To the northeast is Al-Khwarizmi.

The outer rim of Saenger has been eroded and reshaped by subsequent impacts, leaving the outer wall nearly destroyed to the north and south. The satellite crater Saenger D is adjacent to the interior of the northeastern rim. To the west, Saenger V lies across the northwestern rim, while the crater pair Saenger P and Q lie across and intrude into the southwestern rim. In contrast, the interior floor is relatively flat and featureless, with only tiny craterlets to mark the surface.

## Satellite craters

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