Singleton's Graveyard is an historic plantation cemetery located off SC 261 in the High Hills of Santee, 6 miles south of Wedgefield, South Carolina.

It was designed by noted sculptor Ottaviano Gori of New York City.

[2] William Tennant (1740-1777], noted Presbyterian minister and politician, is believed to be buried here, since his widow recorded in their family Bible that he died at "Captain Singleton's High Hills of Santee, August 11, 1777 ...".

[2] Sarah Angelica Singleton, daughter of Col. Richard Singleton and his wife, Rebecca Travis Coles, married Abraham Van Buren on November 27, 1838, at her parents’ home in Wedgefield.

Her father-in-law, Martin Van Buren, was then eighth[5] President of the United States and she served as First Lady during the rest of his time in the White House.
