State Route 319 (SR 319) is a state highway in southeast Tennessee, starting at the intersection of SR 153 in Chattanooga, traveling to the area of Soddy-Daisy where it intersects with US 27, and the route comes to an end.

SR 319 begins on the northeast side of Chattanooga at SR 153 as a segment of Amnicola Highway. SR 319 then turns north as DuPont Parkway to have an interchange with Access Road and Hixson Pike. It then turns east, junctions with SR 153, turns back north along SR 153 and begins a very short 0.7 mile-long concurrency. It again interchanges and becomes concurrent with Hixson Pike, turning northeast and leaving Chattanooga/Hixson 3.7 miles from SR 153. SR 319 then enters the community of Middle Valley and after 3.3 miles it leaves Middle Valley corporate limits and enters the city of Lakesite. In this area it turns back and forth from east to north. After it leaves Lakesite it passes the Sequoyah Nuclear Plant, turns northwest and enters Soddy-Daisy city limits to end at US 27/SR 29.

This section is missing mileposts for junctions. Please help by adding them.

The entire route is in Hamilton County.
