Eponym	Henri Chrétien

Chrétien is a lunar crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side. The crater lies in the mid-point between the craters Garavito to the west-southwest and Oresme to the east-northeast, both of these being somewhat smaller than Chrétien.

The most notable feature of this crater is the low albedo interior floor, which has the same darker hue as the Mare Ingenii to the north. The irregular satellite crater Chrétien C, which shares the straight and narrow northeastern rim of Chrétien, is also covered with this dark basaltic lava. The outer rim of Chrétien is irregular in shape, with several other satellite craters intruding into the sides. The most notable of these are Chrétien S across the southwest rim, and Chrétien W attached to the northwest rim.

The northern rim of Chrétien has a break that joins a small, irregular plain. This area has been resurfaced by the same lava flows that covered the interior of Chrétien. At the southern end, the inner wall forms a wide, irregular surface while the damaged rim bulges outward to the south.

Satellite craters

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 Chrétien.
