The Monticello Association is a non-profit organization founded in 1913 to care for, preserve, and continue the use of the family graveyard at Monticello, the primary plantation of Thomas Jefferson, the third President of the United States. The organization's members are lineal descendants of Thomas Jefferson and his wife Martha Wayles Skelton Jefferson. The site is located just outside Charlottesville, Virginia. Thomas Jefferson was the designer, builder, owner, and, with his family, a first resident of Monticello.
