David Vann (January 1, 1800 - December 23, 1863) was a sub-Chief who was elected Treasurer of the Cherokee Nation in 1839, 1843, 1847 and 1851. He was the nephew of the Cherokee chief James Vann and the first cousin of Joseph Vann. He was a member of the Treaty party that supported negotiation with the United States for voluntary emigration of the Cherokee people to the West, in order to secure their rights. Its leaders signed the Treaty of New Echota in 1835, leading to the Cherokee removal in 1838-1839. During the American Civil War, Vann was killed by Pin Indians (Cherokee supporting the Union) in 1863.
