Eimmart is a lunar impact crater that is located near the east-northeastern limb of the Moon, to the northeast of the Mare Crisium. The northern and eastern outer rim of this crater borders on the narrow Mare Anguis. To the northwest of Eimmart are the smaller crater Delmotte and the prominent Cleomedes.

The rim of this crater has been lightly eroded, especially along the south-southeastern portion, but most of the edge remains intact. The small crater Eimmart A lies along the eastern rim, and is surrounded by a skirt of higher albedo material, particularly to the south and west across the interior of Eimmart. The interior floor is relatively level, and is marked by the ray material from Eimmart A.

Mare Anguis is the dark patch in the middle of this photo. The crater in the left center of the photo is Eimmart, and is at the northwestern tip of Mare Anguis.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Eimmart.
