Graff is a small lunar crater that lies along the southwestern limb of the Moon. It is located to the west of the Vallis Bouvard depression in the southern part of the ejecta blanket that surrounds the Mare Orientale impact basin. To the south-southwest is the smaller Catalán crater.

The outer rim of this crater is roughly circular, with a slight outward protrusion along the southern side. The rim and inner walls are not significantly eroded, and slope downward to a ring of accumulated debris surrounding the interior floor. The bottom is somewhat irregular, with a tiny crater near the mid-point and another to the northeast.

Because of its location, this crater is viewed from the side by observers on the Earth, and the visibility of this formation can be affected by libration.

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 Graff crater.
