The Anderson River is a tributary of the Ohio River in southern Indiana in the United States. Via the Ohio, it is part of the watershed of the Mississippi River.
The Anderson rises in western Crawford County in the Hoosier National Forest and flows generally southwardly through southeastern Dubois County and along the common boundary of Perry and Spencer counties, east of the town of Saint Meinrad. It joins the Ohio River just downstream of the town of Troy.
Near its mouth it collects the Middle Fork Anderson River, which flows for its entire length in Perry County.
