Birt is a lunar impact crater that is located in the eastern half of the Mare Nubium. To the east of the crater is the Rupes Recta, a long, linear feature commonly called the Straight Wall. In actually this is only a slight rise in the surface of the mare with a maximum height of about 240 meters. It has a width of about 2.5 kilometers and is 100 kilometers in length.

Birt is a bowl-shaped formation with a raised rim. It is slightly intersected along the southeast rim by the much smaller crater Birt A. To the west of Birt, a rille named Rima Birt runs north-northwest in an arc from Birt F to Birt E.

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 Birt.
