State Route 456 (SR 456) is a 10-mile-long (16 km) north–south state highway in Scott County, Tennessee. It serves as a bypass of Huntsville for traffic on SR 297. It was originally part of SR 297 until it was moved in the 2000s to follow more of SR 63 and part of US 27 in Oneida.

SR 456 begins at an intersection with SR 63/SR 297 just east of Huntsville, where the road continues south into Winona as Winona Road. It goes north as Annadell Road past businesses, homes, and then farmland to come to an intersection with Paint Rock Road. The highway then turns left onto Paint Rock Road begins to head into mountainous terrain as it goes northwest through a narrow and long valley. It passes through the community of Paint Rock before winding its way northwest through mountains to enter Oneida. SR 456 passes by several businesses and homes before crossing a bridge over a railroad track and entering downtown. It heads west as Depot Street along the south side of downtown before coming to an end at an intersection with US 27/SR 29, just feet from that highway's intersection with SR 297.^[1][2]

The entire route is in Scott County.
