Notropis is a genus of freshwater ray-finned fish in the family Leuciscidae, the shiners, daces and minnows. They are known commonly as eastern shiners.[http://www.cbif.gc.ca/acp/fra/siti/regarder?tsn=163399 Notropis] Système canadien d’information sur la biodiversité (SCIB) They are native to North America, and are one of the continent's most speciose genera.McAllister, C.T., Layher, W.G., Robison, H.W. & Buchanan, T.M.

A 1997 phylogenetic analysis placed the genus in a clade with Campostoma, Cyprinella, Phenacobius, Platygobio and Rhinichthys.Simons, A.M. & Mayden, R.

The systematics of the genus is still unclear. It has not been confirmed to be monophyletic. While it has been divided into several subgenera and species groups, the relationships between the taxa are not yet understood.Cashner, M.F., Piller, K.R. & Bart, H.L.
