State Route 56 (SR 56) is a 160.6-mile-long (258.5 km) state highway that runs south to north in Middle Tennessee, from the Alabama state line near Sherwood to the Kentucky state line near Red Boiling Springs.
SR 56 is secondary south of Sewanee. It is primary (but unsigned) along US 41A and US 41 between Sewanee and Tracy City.
