Franklin is a lunar impact crater that is located in the northeast part of the visible Moon; it is named after Benjamin Franklin. To the north-northwest is the smaller crater Cepheus, and in the opposite direction to the southwest is the shallow Berzelius.

The rim of Franklin is generally circular, with a pair of outward bulges in the western wall. The inner wall is terraced, and there is a central peak at the midpoint of the floor. A narrow cleft runs to the west-southwest across the floor, passing to the north of the central peak.

Satellite craters[edit]

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