John Dash Van Buren (March 18, 1811 in New York City – 1885 in Newburgh, Orange County, New York) was an American merchant and politician from New York. He was the son of Michael Van Beuren (1786–1854) and Anne (Dash) Van Beuren. He graduated from Columbia College in 1829. Then he studied law in the office of Hugh Maxwell, but soon abandoned this and became a merchant instead. On March 30, 1836, he married Elvira Lynch Aymar (1817–1898), and they had four children, among them State Engineer John D. Van Buren Jr. (1838–1918). He was Gov. John T. Hoffman's private secretary from 1869 to 1872.
