William Tennent Stockton (October 9, 1812 – March 4, 1869) was an American soldier and mayor of Quincy, Florida.

One of William's brothers, Richard Lucius Stockton, served with Davy Crockett's Tennessee Mounted Volunteers until his death at the fall of the Alamo.

After graduating, Stockton was first stationed at the Augusta Arsenal in Georgia, and then at Fort Macomb in Louisiana, as a second lieutenant of the Second U.S.

[5] In the early 1840s, Stockton and his brother Philip moved to Quincy to open and operate a stagecoach line that ran mail between Mobile, Alabama, and St. Augustine, Florida.

[9] Following Florida's secession in January 1861, Stockton raised a company of cavalry out of Quincy called the Gadsden Dragoons.

[9][a] During the Chattanooga campaign, the Florida Brigade of the Army of Tennessee, which included the now dismounted 1st Cavalry, were stationed on picket duty at the base of Missionary Ridge when Union forces attacked on November 25, 1863.

Stockton said that because he was still recovering from the wound he had incurred at Chickamauga, he was "unable from exhaustion, to leave the field".
