Newton Horace Winchell ( -May 2, 1914) was the extermely prolific Minnesota geologist responsible for the six-volume The Geology of Minnesota: Final Report of the Geological and Natural History Survey of Minnesota, which is the work of Winchell and his assistants. A bibliography of his publications by Warren Upham in the Bulletin of the Geological Society of America (volume 26, pp. 27-46) contains almost 300 titles.

Born in New York State, Winchell passed his career in Minnesota, where he settled in 1872. When he accompanied the Custer expedition to the Black Hills of South Dakota in 1874, Winchell prepared the first geological map of that area. Winchell was also one of the founders of the Geological Society of America, a chief organizer of the Minnesota Academy of Sciences, and president of several societies.

Winchell's geological examination of the Kensington Runestone has been adduced to suggest that the runestone is authentic.
