Collierville is a town in Shelby County, Tennessee, United States, and a suburb located in the Memphis metropolitan area. The town had a population of 43,965 at the 2010 census.
Collierville is a mainly upscale town of large houses and considerable retail expansion, but unlike its neighbors, still retains much of its "old town" feel from its days as a self-contained community, rather than a suburb. Smaller, older houses are still found in the heart of Collierville, mainly between Byhalia Road and Collierville-Arlington on the east and west and Shelton and Highway 72 on the north and south. Some industry, notably Pepsi and Carrier, still dots the areas located south of Poplar Avenue.
Collierville is home to the Avenue at Carriage Crossing, an 800,000+ sq ft shopping center which opened in October 2005. Baptist Hospital, Collierville, serves the medical needs of the town's residents.
