Euler is a lunar impact crater located in the southern half of the Mare Imbrium. The most notable nearby feature is Mons Vinogradov to the west-southwest, which was formerly named Mons Euler. There is a cluster of low ridges to the southwest, and this formation includes the small crater Natasha and the tiny Jehan. To the southwest is the 105-km diameter Rima Euler, which is named after the crater. About 200 kilometers to the east-northeast is the comparably sized crater Lambert.
