Leuschner is a lunar impact crater that is located on the Moon's far side, to the northwest of the Montes Cordillera. It lies to the north of the crater Grachev, in the outer skirt of ejecta surrounding the Mare Orientale impact basin. This is a circular crater with a rim that has only been lightly eroded by subsequent impacts. Within the interior floor is a central ridge formation. The infrared spectrum of pure crystalline plagioclase has been identified on the central peak.
