Elvey is a lunar crater that is located on the far side of the Moon. It is located near the northern edge of the blanket of ejecta that surround the Mare Orientale impact basin. To the north of Elvey is the smaller Nobel crater.

This is a damaged crater with a rim that is only partly intact along the eastern side. The remainder of the rim is irregular and less distinct. This condition may have been created by the ejecta from the Mare Orientale impact to the south. A pair of small craters lie along the northwestern rim.

Less than two crater diameters to the south of Elvey is the impact site of a small crater. This formation lies at the focus of a ray system that extends over 200 km in all directions. The central portion of this system forms a bright skirt of higher albedo materila, while the rays become progressively more wispy with distance. There is a larger but less distinct ray system further to the northwest of Elvey, and these two system criss-cross each other along a section of terrain containing Elvey.
