The moapa dace, Moapa coriacea, is a rare cyprinid fish of Southern Nevada, United States, found only in the warm springs that give rise to the Muddy River, and in the upper parts of the river.

A small fish, with a maximum recorded length of 9 cm, its scales are small and embedded in the skin, resulting in a noticeably leathery texture (thus the species epithet, derived from Latin coriaceus "leathery"). General body shape is standard for cyprinids, with a vaguely conical head.

Moapa daces require warm water, in temperature range of 87 to 93 °F.
