Krieger is a lunar crater on the eastern part of the Oceanus Procellarum. It is located to the north-northwest of the flooded crater Prinz, and north-northeast of the prominent Aristarchus crater. To the northwest lies the small Wollaston crater. In the past the floor of Krieger crater has been flooded by basaltic lava, leaving only a low, circular, somewhat polygonal ridge formed by the rim. The southern rim is broken across by the small Van Biesbroeck crater, and there is a small gap in the western rim. A meandering rille leads away from this break toward the northwest.

Nearby craters
Two tiny craters next to the eastern rim have been designated Rocco and Ruth. Rocco was previously designated as 'Krieger D' before being named by the IAU.
| Crater | Longitude | Latitude | Diameter | Name source |
|---|---|---|---|---|
| Rocco | 28.9° N | 45.0° W | 5 km | Italian masculine name |
| Ruth | 28.7° N | 45.1° W | 3 km | Jewish feminine name |
The nearby surface to the southwest contains a number of rilles belonging to the Rimae Aristarchus and Rimae Prinze rille systems. Further to the east-southeast are the Montes Harbinger mountains.
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 Krieger crater.
