Puryear is a city in Henry County, Tennessee, United States. The population was 671 at the 2010 census.

Puryear was originally named Littleton in honor of James T. Littleton, a farmer and Confederate States Army veteran who donated a portion of his land to the Paducah, Tennessee and Alabama Railroad to use as a right of way. Its name was changed to Puryear at the suggestion of Littleton's son, James Graves Littleton, when the Nashville, Chattanooga and St. Louis Railway took control of the railroad and mandated it be changed so as not to conflict with the name of either a town in Georgia or Littleton, North Carolina.

Puryear is located in northern Henry County at 36°26′41″N 88°20′2″W / 36.44472°N 88.33389°W / 36.44472; -88.33389 (36.444853, -88.333770).
