Almanon is a lunar impact crater that lies in the rugged highlands in the south-central region of the Moon. It is located to the south-southeast of Abulfeda crater, and to the north-northeast of the smaller Geber crater. The crater chain designated Catena Abulfeda forms a line between the south rim of Abulfeda crater and the north rim of Almanon crater, continuing for a length of about 210 kilometers to the Rupes Altai scarp.

The rim of Almanon forms a slightly distorted circle, with outward bulges to the north and southwest. The crater pair 'Almanon A' and 'Almanon B' is attached to the exterior of the southern rim. The interior wall is wider along the eastern side than eslewhere. Small craters belonging to the Catena Abulfeda intrude slightly into the northeast rim. The outer wall is generally worn and lacks the crispness of a younger crater, but is not significantly impacted by subsequent cratering. The interior floor is relatively flat and lacks notable features other than a few tiny craterlets.

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 Almanon crater.
