William Giles Harding (1808 – December 15, 1886) was a Southern planter, attorney, and horse breeder who was made a Brigadier General in the Tennessee militia before the American Civil War. He took over operations of Belle Meade Plantation near Nashville from his father in 1839. During the course of his management, he acquired more property, expanding it from 1300 acres to 5,400 acres (22 km2) in 1860. He specialized in breeding and raising Thoroughbred horse, as well as other purebred livestock. In 1862 after Union forces took over Nashville, Harding was arrested as a leader and imprisoned at Fort Mackinac in northern Michigan on Mackinac Island for six months. He was released on a $20,000 bond.
