John Randolph Tucker (December 24, 1823 – February 13, 1897) was an American lawyer, author, and politician from Virginia. From a distinguished family, he was elected Virginia's attorney general in 1857 and after re-election served during the American Civil War (James S. Wheat served as attorney general in Union-held portions of the state). After a pardon and Congressional Reconstruction, Tucker was elected as U.S. Congressman (1875-1887), and later served as the first dean of the Washington and Lee University Law School.
