John Price Buchanan was an American politician and farmers' advocate. He served as the 25th governor of Tennessee from 1891 to 1893, and was president of the Tennessee Farmers' Alliance and Laborers' Union in the late 1880s. Buchanan's lone term as governor was largely marred by the Coal Creek War, an armed uprising by coal miners aimed at ending the state's convict lease system.

The Coal Creek War was an early 1890s armed labor uprising in the southeastern United States that took place primarily in Anderson County, Tennessee. This labor conflict ignited during 1891 when coal mine owners in the Coal Creek watershed began to remove and replace their company-employed, private coal miners then on the payroll with convict laborers leased out by the Tennessee state prison system.
