John Gray (January 6, 1764 – March 29, 1868) was one of the candidates for last surviving U.S. veteran of the American Revolutionary War. He was advertised as such by journalist James Dazell and as of 1876 was believed by the Pension Office of the U.S. Department of the Interior to be the last surviving veteran. A memorial to Gray is located along State Route 821 in Noble County's Noble Township.
