State Route 147 (SR 147) is an east–west state highway that traverses Benton County in West Tennessee and Houston County in Middle Tennessee.

The route is 23.64 miles (38.04 km) long, and it crosses Kentucky Lake/Tennessee River via a ferry boat.

It goes north as Main Street before curving east onto Front Street, then turns north onto 2nd Street, crosses a bridge over a creek, before turning east onto Lick Creek Road to leave Big Sandy.

The highway then passes through wooded areas as it turns northeast and becomes curvy before reaching the Danville Ferry to cross Kentucky Lake/Tennessee River into Houston County and Middle Tennessee.

The ferry between Benton and Houston counties began operation in November 2007.
