John Calvin Brown was a Confederate Army officer and an American politician and businessman. Although he originally opposed secession, Brown fought for the Confederacy during the American Civil War, eventually rising to the rank of major general. He later served as the 19th Governor of Tennessee from 1871 to 1875, and was president of the state's 1870 constitutional convention, which wrote the current Tennessee State Constitution.

The general officers of the Confederate States Army (CSA) were the senior military leaders of the Confederate States of America during the American Civil War of 1861–1865. They were often former officers from the United States Army before the Civil War, while others were given the rank based on merit or when necessity demanded. Most Confederate generals needed confirmation from the Confederate States Congress, much like prospective generals in the modern U.S. armed forces.
