Elliott Danforth (March 6, 1850 – January 7, 1906) was an American lawyer and politician.
He was born on March 6, 1850, in Middleburgh, Schoharie County, New York, the son of Peter S. Danforth, a justice of the New York Supreme Court. He studied law with his father and was admitted to the bar in 1871. On December 17, 1874, he married Ida Prince, and they had a son, Edward Danforth, and a daughter. In 1878, he removed to Bainbridge, N.Y., where his father-in-law was President of the First National Bank. There, Danforth practiced law in partnership with George H. Winsor, and was President of the Corporation of Bainbridge.
He was a delegate to the 1880 and 1884, 1888, 1892, 1896, 1900 and 1904 Democratic National Conventions.
He was Deputy Treasurer under Lawrence J. Fitzgerald from 1885 to 1889, and was New York State Treasurer from 1890 to 1893, elected in 1889 and 1891.
In November 1891, he was a member of the State Board of Canvassers (made up by the Secretary of State, Treasurer, Comptroller, Attorney General and State Engineer), when the electoral fraud in the Dutchess County senatorial election happened by which Governor David B. Hill gained control of the New York State Senate. The Republican candidate Gilbert A. Deane had received 78 votes more than Democrat Edward B. Osborne, but the Board changed 92 votes and declared Osborne elected by a plurality of 14. The New York Supreme Court issued a writ to Danforth, ordering him to certify the election of Deane, but Danforth refused to obey. For this he and the other members of the Board were fined $500 by Justice D. Cady Herrick. The sentence was later upheld by the New York Court of Appeals.
