Dreyer is the remnant of a lunar crater on the far side of the Moon. It is located along the eastern edge of the Mare Marginis, about midway between Ginzel crater to the north and Erro crater to the south-southeast.
The rim of this crater is heavily worn, with multiple impacts overlaying the edge and a small gap at the south end. Satellite crater 'Dreyer C' lies across the northeastern rim, while 'Dreyer K' is intruding into the southeastern side. The interior floor is relatively level and featureless, with a few tiny craterlets marking the surface. There is a low central ridge at the mid-point.

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 Dreyer crater.
