The Yalobusha River is a river, 165mi long, in north-central Mississippi in the United States. It is a principal tributary of the Yazoo River, via which it is part of the watershed of the Mississippi River.The name "Yalobusha" comes from the Choctaw word yalooboshi, meaning "little tadpole", from yalooba, "tadpole", and -ushi, "diminutive". The United States Board on Geographic Names settled on the river's name in 1892. According to the Geographic Names Information System, it has also been known as "Yallabusha" and as the "Yellowbushy River."CourseThe Yalobusha River rises in Chickasaw County, northwest of the town of Houston, and flows generally west-southwestwardly through Calhoun, Grenada and Leflore Counties, past the town of Grenada. At Greenwood it joins the Tallahatchie River to form the Yazoo River.
