John Price Buchanan (1847–1930) was governor of the U.S. state of Tennessee from 1891 to 1893. He was a native of Williamson County, Tennessee.
Official state records refer to him as the 28th Tennessee governor. A former two-term member of the Tennessee House of Representatives (1887-1890) representing his adopted home of Rutherford County, Buchanan's term in office was marked by violence in the East Tennessee coal mines, which was eventually put down by the State Guard. The Confederate pension system was put in place during his tenure, as were state-supported secondary public schools. He returned to farming after one two-year term as governor and did not subsequently hold public office.
