Warren County is a county located in the central part of the U.S. state of Tennessee. As of the 2010 census, the population was 39,839. Its county seat is McMinnville.

Warren County comprises the McMinnville, TN Micropolitan Statistical Area.


Warren County was created by European Americans in 1807 from a portion of White County, and named for Joseph Warren (1741–1775), a soldier in the American Revolution. The revised Tennessee State Constitution of 1834 stated that no new county could be within 12 miles (19 km) of the county seat of the county from which it was formed. The boundaries of five counties formed from Warren— Grundy, Van Buren, Cannon, Coffee and DeKalb— were exactly 12 miles from Warren's county seat, McMinnville, giving the county its distinctive round shape.

Warren County citizens remained loyal to the state of Tennessee during the War for Southern Independence. The county voted for independence from the union of States in February 1861 in a State referendum. Tennessee as a whole decided to remain in the union of states at that time. After Lincoln's call for invasion of neighboring states in April 1861, which was seen by Tennessee as a violation of Article 3 Section 3 of the U.S. Constitution, Warren County, along with now a majority of other Tennessee counties voted for independence in the following month of June 1861. Slavery was never mentioned as a cause in the declaration of Tennessee secession. Men from Warren county and surrounding upper Cumberland region formed and served in many units in Tennessee's defense including the 16th Tennessee Infantry [1] lead by McMinnville, TN resident Col. John Houston Savage. The Confederate monument [2] located next to the county courthouse is dedicated in the memory of the men who served and died in the 16th and list their names.

Historically dominated by yeomen farmers who owned few or no slaves, Warren County was the site of several saltpeter mines. Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from several local caves. Hubbards Cave, near Camp Woodlee, was a major operation. Henshaw Cave on Cardwell Mountain (now part of Cumberland Caverns) and Solomon Saltpeter Cave on Ben Lomond Mountain were relatively small mining operations. Most saltpeter mining occurred during the War of 1812 and in the War Between the States.

According to the U.S. Census Bureau, the county has a total area of 434 square miles (1,120 km2), of which 433 square miles (1,120 km2) is land and 1.4 square miles (3.6 km2) (0.3%) is water. The county lies long the Eastern Highland Rim, near the Cumberland Plateau.

The Caney Fork forms part of the county's borders with White and DeKalb counties to the north. The Rocky River, a tributary of the Caney Fork, forms part of the county's western border with Van Buren County. The Collins River, also a tributary of the Caney Fork, flows through the county, and the Barren Fork, a tributary of the Collins, flows through McMinnville.

Cardwell Mountain is an imposing natural feature located five miles due east of McMinnville. It is an erosional remnant of the nearby Cumberland Plateau. Cardwell Mountain is noted for Cumberland Caverns, an exceptionally long cave which lies underneath the mountain.
