State Route 319 (SR 319) is a very short, two-lane state highway in the western portion of the U.S. state of Ohio. A spur route, SR 319 has its western terminus at an abandoned railroad grade just west of Washington Street in the village of Burkettsville. Its eastern terminus is 0.56 miles (0.90 km) to the east of its western terminus at its junction with SR 118. SR 319 was established in the early 1930s. It started out as a much longer highway, but earlier segments would become a part of SR 118 in the late 1930s.
