Perrine is a lunar crater that is located on the northern hemisphere on the far side of the Moon. It lies to the west of the large Landau walled plain, and to the northeast of Charlier crater. To the north-northwest is the smaller Gullstrand crater.

This is an unusual formation that forms part of a chain of connected craters. The western two-thirds of Perrine is overlaid by the slightly smaller 'Perrine S', so that Perrine is a crescent-shaped formation. The western rim of 'Perrine S' is overlaid by the still smaller 'Perrine T'. 'Perrine S' has a worn outer rim, and a small central peak in the middle of the floor.

The surviving rim of Perrine is worn and eroded, with the overlapping pair 'Perrine E' and 'Perrine G' intruding slightly into the eastern rim. A smaller crater has disrupted the southwest end of the outer rim, and a pair of small craters are attached to the northern rim.

Only a small portion of the interior floor of Perrine still survives, forming a crescent-shaped surface between the outer rampart of 'Perrine S' and the inner wall of Perrine. It is marked by a pair of tiny craterlets in the northern half.

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 Perrine crater.
