Isidorus is a lunar crater that is located to the north of the Mare Nectaris, on the eastern half of the Moon's near side. It forms a pair with the slightly larger Capella crater, which is attached to the east-northeastern rim. To the west-southwest across the lunar mare are Mädler and the prominent Theophilus craters.

The rim of Isidorus is circular and somewhat eroded, with several tiny craterlets laying across the northern rim. The interior floor has been resurfaced by lava and is generally level, although it is marked by a small, bowl-shaped crater 'Isidorus A' along the western rim. There is a tiny remnant of a craterlet attached to the northern rim of this last formation.

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 Isidorus crater.
