The southern redbelly dace (Chrosomus erythrogaster), is a North American species of temperate freshwater fish of the family Cyprinidae.

The natural geographic range extends from Western New York to Minnesota, and south to Oklahoma, Arkansas, and Alabama.

[2] The extremely similar northern redbelly dace can be distinguished by a rounder, blunter head and a more upturned mouth, as well as by differences in spawning behavior.

[5] The southern redbelly dace lives in clear, flowing bodies of water, typically streams and rivers.

[citation needed] The southern redbelly dace is an important environmental indicator of river and stream health.
