Camp Morton was a military training ground and a Union prisoner-of-war camp in Indianapolis, Indiana, during the American Civil War. It was named for Indiana governor Oliver Morton. Prior to the war, the site served as the fairgrounds for the Indiana State Fair. During the war, Camp Morton was initially used as a military training ground. The first Union troops arrived at the camp in April 1861. After the fall of Fort Donelson and the Battle of Shiloh, the site was converted into a prisoner-of-war camp. The first Confederate prisoners arrived at Camp Morton on February 22, 1862; its last prisoners were paroled on June 12, 1865. At the conclusion of the war, the property resumed its role as the fairgrounds for the Indiana State Fair. In 1891 the property was sold and developed into a residential neighborhood known as Morton Place, a part of the Herron-Morton Place Historic District.
