Herigonius is a small lunar impact crater that is located in the southern part of the Oceanus Procellarum, to the northeast of the crater Gassendi, and is named after Pierre Hérigone. Herigonius is roughly circular, with an inward bulge and narrower inner wall along the northeast. In the interior of the sloping inner walls is a floor about half the diameter of the crater.

About 60 kilometers to the west of Herigonius is a sinuous rille designated Rima Herigonius. This cleft is about 100 kilometers in length and runs generally in a north-south direction, while curving to the east at the north end.

North and northwest of the crater is Dorsa Ewing, a ridge it also touches Rimae Herigonius.

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 Herigonius.
