The Sunflower River is one of the main tributaries of the Yazoo River in the U.S. state of Mississippi. The Sunflower follows an old channel of the Mississippi River as it winds between farms, neighborhoods, wetlands and abandoned sharecropper shacks. It is navigable by barge for 50 miles. It rises in DeSoto County, Mississippi near the Tennessee border and flows south for 100 miles to the Yazoo River, a major tributary of the Mississippi River. At Clarksdale, the county seat of Coahoma County, the annual Sunflower River Blues & Gospel Festival is held.
