Purbach is a large lunar crater located in the rugged southern highlands of the Moon. The distorted crater Regiomontanus is attached to the southern rim. To the northwest is Thebit crater and just to the northeast lies the La Caille crater.
The outer wall of Purbach is heavily worn, with the most intact section being along the east and northeast sides. The shared rim between Purbach and Regiomontanus is incised and rugged. The wall is distorted along the western edge, giving the appearance of a double-rim, with the second rim distended toward the west. The northern wall is almost completely destroyed, and somewhat irregular 'Purbach G' lies across the northwest rim.
The crater floor is relatively smooth in the eastern half, with a low series of ridges and a partial "ghost-crater" outline just to the west of the crater mid-point. If the crater possessed a central peak, it has either been removed or forms part of the ridges to the west.

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 Purbach crater.
