Endymion is a lunar crater that lies near the northeast limb of the Moon. It is located to the east of Mare Frigoris, and north of the Lacus Temporis. To the southwest is the somewhat smaller crater Atlas. Because of its location, Endymion has an oval appearance from foreshortening. Beyond the crater along the lunar limb is the Mare Humboldtianum.

The floor of Endymion has been covered in low-albedo lava that gives it a dark appearance and makes it relatively easy to locate. The floor is nearly smooth and featureless, with only a few tiny craterlets located within the rim. A string of three lie near the northwestern inner wall. Faint streaks of ray material from Thales to the north-northwest crosses the dark floor. The outer rampart is low, wide, and worn from impact erosion.

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 Endymion.
