Etheostoma is a genus of small freshwater fish in the family Percidae native to North America. Most are restricted to the United States, but species are also found in Canada and Mexico. They are commonly known as darters, although the term "darter" is shared by several other genera. Many can produce alarm pheromones that serve to warn nearby fish in case of an attack.
