Warren County was officially founded in 1836. It was formed from parts of Frederick and Shenandoah Counties. The Town of Front Royal has been the county seat from the beginning. In 1840, Warren County had a population of 5,627.

Warren County was of strategic importance during the Civil War because of its agricultural productivity, transportation links with Winchester to the north, and its links with eastern Virginia by way of the roads through Chester and Manassas Gaps and the vital Manassas Gap Railroad.

The Battle of Front Royal, on May 23, 1862, was one of the Battles in General Stonewall Jackson's famous Valley Campaign. In that battle, Confederate forces defeated 1,000 Union soldiers to capture a military supply depot, the Manassas Gap Railroad, and the strategic bridges over the two forks of the Shenandoah River at Riverton.

Warren County has long attracted tourists and residents that come to the area because of its climate, accessibility to major cities, and scenic beauty. Major tourist attractions include the Shenandoah River, Shenandoah National Park, Shenandoah River/Raymond R. Andy Guest, Jr. State Park, and Skyline Caverns.
