Birt is a lunar impact crater located in the eastern half of the Mare Nubium and west of the Rupes Recta, further west is Nicollet and south-southwest is the smaller Lippershey.

Birt is a bowl-shaped formation with a raised rim, slightly intersected along the southeast edge 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.
