Euclides is a small lunar impact crater located near the eastern edge of Oceanus Procellarum, about 30 kilometers to the west of the Montes Riphaeus mountains. The mare in the vicinity is devoid of significant craters, but to the west is an area of low rises. The crater is named after the Greek mathematician Euclid.

The Euclides is a bowl-shaped formation with a circular rim. It is surrounded by streaks of "ejacta" that have a higher albedo than the nearby "maria". This nebulous skirt of light-hued material makes this feature very prominent under a high sun, and it is one of the brightest sites on the Moon.

Euclides D

'Euclides D' is a small lunar impact crater in the Mare Cognitum. It has a diameter of 6 kilometers and a depth of 1.3 kilometers. It lies to the southeast of Euclides crater, beyond the Montes Riphaeus mountains.

In 1976, 'Euclides D' was renamed by the IAU to "Eppinger" to honor Hans Eppinger, a professor of pathological anatomy at Graz. However in 2002, after Eppinger's association with Nazi prison camps had been brought to the attention of the "Working Group for Planetary System Nomenclature", the name was changed.

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 Euclides crater.

The following craters have been renamed by the IAU.
* Euclides B — "See" Norman crater.
