Brashear is a lunar impact crater on the far side of the Moon, in the southern hemisphere in the vicinity of the south pole.

[1] It lies just to the south of the walled plain Antoniadi, within the larger crater's outer rampart of ejecta.

To the northeast besides Antoniadi is the crater Numerov, and southeast lies the younger De Forest.

This formation is little more than a shallow depression in the lunar surface, its features eroded and blanketed by the ejecta from the relatively fresh crater Antoniadi just to the north.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Brashear.
