'''''Lythrurus''''', the '''finescale shiners''', is a genus of freshwater ray-finned fishes belonging to the family Leuciscidae, the shiners, daces and minnows. The fishes in this genus are found in North America.
==Taxonomy== ''Lythrurus'' was first proposed as a genus in 1876 by the American ichthyologist David Starr Jordan with ''Semotilus diplemia'' as its type species.<ref name = "Cof family"/> ''S. diplemia'' had been formally described in 1820 by the French polymath Constantine Samuel Rafinesque. However, ''S. diplemia'' is now regarded as a synonym of ''Chrosomus erythrogaster''<ref name = "Cof genus">{{Cof genus|genus=Lythrurus|access-date=16 March 2025}}</ref> and in 1884 Jordan proposed ''Notropis lythrurus'' as the type species, this taxon is a synonym of ''Notropis umbratilis''. If ''S. diplemia'' is the type species then ''Lythrurus'' is a synonym of ''Chrosomus'' and if this taxon is a valid genus then a new name is needed for this taxon. This genus is classified within the subfamily Pogonichthyinae of the family Leuciscidae.<ref name = "Cof family"/>
