Polk County is a county located in the southeastern corner of the U.S. state of Tennessee. As of the 2016 census estimate, the population was 16,773.  Its county seat is Benton.  The county was created on November 28, 1839, from parts of Bradley and McMinn counties. The county was named after then-governor (and future president) James K. Polk.
According to the U.S. Census Bureau, the county has a total area of 442 square miles (1,140 km2), of which 435 square miles (1,130 km2) is land and 7.7 square miles (20 km2) (1.7%) is water.

Much of the terrain of eastern Polk County is mountainous, including Big Frog Mountain, constituting part of the southern Appalachian Mountains. Large tracts of Polk County are part of the Cherokee National Forest. The Ocoee River, site of whitewater slalom events in the Atlanta 1996 Summer Olympic Games, runs through Polk County and is vital to one of the county's major industries, whitewater rafting. The calmer Hiwassee River, a tributary of the Tennessee River which flows through northern Polk County, is also used for rafting and tubing.

Copper was discovered in Ducktown in 1843, and by the 1850s a large mining operation was taking place here. This operation continued until the 1970s, when the last mine closed.
In 1973, a large music festival known as the "Midwest Monster Peace Jubilee and Music Festival", commonly known as the "Monster Peace Jubilee", was planned by Indiana-based promoter C.F. Manifest Inc. to take place on a 1,300 acre farm north of Benton on Labor Day of that year. Nicknamed "Polkstock" due to its resemblance to 1969's Woodstock in Bethel, New York, the event was expected to attract 500,000 and was strongly opposed by locals, especially the religious community, who believed the festival would bring sex and drugs, as well as much of the perceived rock music culture. While the festival was still in the planning stages, the owner of the farm reportedly received a burning cross in his yard, and, shortly there after, a barn on his property suspiciously burned. The festival was eventually shut down by the state circuit court, on the request of the district attorney, that the festival would constitute a public nuisance, due to drug, health, and traffic problems. 
On May 27, 1983, a massive explosion at an illegal fireworks factory exploded, killing eleven workers. The operation, located on a bait farm a few miles south of Benton, was unlicensed, and produced M-80 and M-100 fireworks, both illegal in Tennessee, and was the largest illegal fireworks operation in the United States to date.
