Bragg is an ancient lunar crater that is located on the far side of the Moon, just beyond the northwest limb. This formation has been heavily eroded and reshaped by subsequent impacts, leaving an irregular depression in the surface. The most intact portion of the rim is along the western face, while the northern and eastern rim has been nearly worn away and is overlaid by several smaller craters. The most notable of these is 'Bragg H', which lies across the east-souteastern rim.
This crater is located to the north-northwest of the Lorentz walled-plain. Nearby craters of note include Rynin to the north, Stefan to the northwest, Lacchini to the west, and Avicenna to the southeast. The region about this crater is very rugged and marked by many smaller 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 Bragg crater.
