State Route 30 is an east-west state highway in the central and eastern portions of the U.S. state of Tennessee. It runs generally west to east, connecting McMinnville in Warren County with Parksville along the Ocoee River in Polk County. It crosses several major geographic features in Tennessee, including the Cumberland Plateau, the Sequatchie Valley, the Tennessee River, and parts of the Cherokee National Forest.

The Sequatchie River is a 116-mile-long (187 km) waterway that drains the Sequatchie Valley, a large valley in the Cumberland Plateau in Tennessee. It empties into the Tennessee River downstream from Chattanooga near the Tennessee-Alabama state line.
