Pontanus is a lunar crater that is located in the southern highlands of the Moon's near side. It lies approximately mid-way between Sacrobosco crater to the north-northeast and Gemma Frisius crater to the south-southwest.
The rim of this crater has been heavily worn by subsequent impacts, leaving a roughly circular, uneven slope about the interior. There is an outward protrusion in the rim to the south. The rim and inner wall to the north is less prominent, and is incised along the inner edge. The satellite crater 'Pontanus V' is attached to the west-southwestern side. The interior floor is relatively uneven, particularly in the northern half, but is not marked by any significant 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 Pontanus crater.
