Barbier is a lunar impact crater that is located on the southern hemisphere on the far side of the Moon. It forms a matched pair with Cyrano to the north-northwest, and it lies to the southeast of the huge walled plain Gagarin. Southwest of Barbier is the crater Sierpinski, and to the southeast is the Mare Ingenii.

The outer rim of Barbier has been eroded somewhat by subsequent impacts, particularly at the north end where the wall has been degraded by several small craterlets. A small crater lies across the eastern rim, and the southern rim is wider and irregular in shape. A small crater lies near where a central peak would be located, offset slightly to the east of the mid-point.

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 Barbier.
