Philadelphia is a city in Loudon County, Tennessee, United States. Its population was 533 at the 2000 census. It is included in the Knoxville Metropolitan Statistical Area.


Philadelphia was founded in the early 1820s by William Knox and Jacob Pearson. The town initially grew quickly and prospered as a center of business in the Sweetwater Valley. By the mid-19th century, Philadelphia had two general stores, a tanning yard, a stillhouse, and a hotel.

On October 20, 1863, during the Civil War, two Confederate cavalry regiments attacked and routed a Union brigade at Philadelphia while conducting maneuvers following the Battle of Chickamauga. The Confederates captured 700 soldiers, 6 cannon, and 50 supply wagons.
