Polybius is a lunar impact crater in the southeast part of the Moon. It is located to the south-southeast of the larger crater Catharina in the area framed by the Rupes Altai scarp. Some distance to the northeast is the Mare Nectaris with the flooded craters Beaumont and Fracastorius.The crater rim of Polybius appears slightly distended in the northeast and has a cut through the northern wall. But the wall is otherwise moderately intact with only minor erosion.
