Römer is a lunar impact crater that is located to the north of the Sinus Amoris in the northeast section of the Moon. It lies in the southwest part of the mountainous region named the Montes Taurus. To the west-northwest is the crater-bay Le Monier, on the east edge of Mare Serenitatis.

The rim of Römer has relatively high walls with a d inner surface. There is a small craterlet on the north part of the floor, and a large central peak at the mid-point.

To the northwest of the crater is a prominent system of rilles named the "Rimae Römer". These follow a course to the north from the west rim of the crater, and have a combined length of about 110 kilometres.
