George Geddes (February 14, 1809 Fairmount, Onondaga County, New York – October 8, 1883 Fairmount, NY) was an American engineer, agronomist, historian and politician from New York.
He was the son of engineer, surveyor and Congressman James Geddes.
George Geddes studied engineering and surveying in Middletown, Connecticut, and law in Skaneateles, New York.
He was a member of the New York State Senate (22nd D.) from 1848 to 1851, sitting in the 71st, 72nd, 73rd and 74th New York State Legislatures. He was one of three state senators instrumental in the passage of the 1848 New York State law permitting women to hold property independently of their husbands, the first of its kind in the United States. He served on the New York State Senate's Indian Affairs committee and wrote articles about Iroquois history and archaeology. Originally a Whig, he later joined the Republican Party. He was a moderate abolitionist.
Geddes was well-known nationally in agricultural circles for his model farm at Fairmount, and was an early mentor to Frederick Law Olmsted. He also built the first plank road in America, at North Syracuse, New York, in 1846.
