Reliance is an unincorporated community in Polk County, Tennessee, United States.

[6][7]The community developed in the latter 19th century when a water-powered grist mill and sawmill were constructed along the river.

[8] A home constructed on the north side of the river in 1878 was expanded into the Higdon Hotel in 1890, initially providing housing for the railroad workers.

The Watchman's House, built in 1891 on the north side of the river, was originally occupied by a railroad watchman, whose job was to watch to ensure trains crossing the bridge over the Hiwassee did not set fire to the bridge.

The Hiwassee Union Church and Masonic Lodge was constructed in the community in 1899, and also served as a school.
