The wounded darter ("Etheostoma vulneratum") is a species of darter endemic to the eastern United States.
 Its range includes the upper Tennessee River drainage, western Virginia, western North Carolina, and eastern Tennessee.
 Its typical habitat is among boulders or coarse rubble and cobble, often with overhanging ledges, in medium to large slow-moving rivers.
 It feeds on small insect larvae, especially midge larvae.
 Spawning occurs when the water warms up in late spring.
 Females deposit clutches of adhesive eggs on the underside of rock ledges or slabs, and the male guards the nest.
 The population trend of this fish seems to be decreasing slowly but it is a relatively common species with numerous sub-populations, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
 The greatest threat comes from impoundment, and a management plan is in place, including captive breeding.
