Joseph Leonard Follett (February 16, 1843 – April 1, 1907) was an American soldier who fought in the American Civil War.

Follett received the country's highest award for bravery during combat, the Medal of Honor, for his action during the Battle of Island Number Ten in New Madrid, Missouri on 3 March 1862 and the Battle of Stones River in Tennessee on 31 December 1862.

The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to Sergeant Joseph Leonard Follett, United States Army, for extraordinary heroism on 3 March 1862, while serving with Company G, 1st Missouri Light Artillery, in action at New Madrid, Missouri.

Sergeant Follett remained on duty though severely wounded.

On 31 December 1862, while procuring ammunition from the supply train at Stone River, Tennessee, he was captured, but made his escape, secured the ammunition, and in less than an hour from the time of his capture had the batteries supplied.
