James DeWitt Hill (2 March 1882 – 7 September 1927) was an early US air mail pilot, who died while attempting one of the first transatlantic flights, with Lloyd Wilson Bertaud in a Fokker F.VIIA monoplane named Old Glory.

He subsequently studied civil engineering at Cornell University, Ithaca, New York, but he was unable to complete that course because of ill health.

[2] In spring 1927, Hill's fellow air mail pilot and friend Lloyd W. Bertaud was approached to be the co-pilot for an attempt at the first flight from New York to Paris, France, flying the Wright-Bellanca WB-2 Columbia.

Bertaud's elimination from the crew of Columbia spurred him to make his own attempt at a transatlantic flight, this time from New York to Rome, Italy, and Hill agreed to join him.

At 3.57 am and 4.03 am distress signals from the aircraft were received by radio; its estimated position was then 960 km east of Cape Race, Newfoundland.

[1] In 1928, the Ontario Surveyor General named a number of lakes in the northwest of the province to honour aviators who had perished during 1927, mainly in attempting transoceanic flights.
