Dugan is a lunar crater that is located on the northern part of the Moon's far side. It lies to the southwest of the large Schwarzschild walled plain, and due north of the Compton crater.
This is a heavily worn and eroded crater with an outer wall that forms an irregular ring of peaks and valleys surrounding the relatively featureless interior floor. The crater is now little more than a circular depression in the rugged lunar terrain. The crater features have a softened appearance, possibly due to overlaying ejecta from the much larger Schwarzschild and Compton impacts.

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 Dugan crater.
