Franz is a small lunar crater that is located along the eastern edge of the Sinus Amoris, a bay that forms a northern extension to the Mare Tranquillitatis. It lies to the southwest of the prominent Macrobius crater. To the north is the smaller Carmichael crater, and to the northwest is the diminutive Theophrastus crater.
The rim of this crater has been eroded due to subsequent impacts, although it retains a generally circular form. The interior has been flooded, leaving only a narrow inner wall and a low surviving rim. This floor has the same albedo as the surrounding terrain, and is not as dark as the lunar mare surface to the north and west. Attached to the exterior of the eastern rim is 'Proclus E', a merged double-crater formation. Proclus crater lies to the east across the Palus Somni, or "Marsh of Sleep".
