Hanno is a lunar impact crater that lies near the southeastern limb of the Moon, along the western edge of the Mare Australe. About a crater diameter to the southwest is the prominent crater Pontécoulant.

Hanno is a heavily worn crater formation with an outer rim that has been battered and pock-marked by small impacts. A small crater attached to the north-northeastern rim forms a depression in the side. The inner walls are nearly featureless except for a few small craterlets, and the interior floor is likewise level and battered by tiny craters.

The Hanno crater was named after Hanno the Navigator.
