Ross Gilmore Marvin (January 28, 1880 – after December 8, 1908; reported as April 10, 1909)[a] was an American explorer who took part in Robert Peary's 1905–1906 and 1908–1909 expeditions to the Arctic.

[1] In 1899, he graduated from the Elmira Free Academy,[1] and in fall of that year he entered Cornell University,[2] where he earned a Bachelor of Arts degree in 1905.

[3] He also studied navigation on the training ship St. Mary's of the New York Nautical School, traveling to Europe and northern Africa.

While Peary set out to reach the North Pole, Marvin was left behind as part of a staged support team.

[1] Peary's expedition placed a brass tablet on a cairn in memorial to Marvin at Cape Sheridan on Ellesmere Island.

[14] The SS Ross G. Marvin, an American Liberty ship named in his honor, was built and launched in 1943.

[15][e] John M. Carmody, chair of the ship-naming committee within the United States Maritime Commission, had attended school with Marvin in Elmira.

[18] A booklet about Marvin, entitled A Tragedy in the Arctic and written by James Vinton Stowell of the Chemung County Historical Society, was published in 1954.
