The Sunflower River (also known as the Big Sunflower River) is one of the main tributaries of the Yazoo River in the U.S. state of Mississippi. It is navigable by barge for 50 miles. It rises in De Soto County, Mississippi near the Tennessee border and flows south for 100 miles to the Yazoo River. At Clarksdale on its banks, the annual Sunflower River Blues and Gospel festival is held.
