William Watson Davis (February 12, 1884 - April 5, 1960) was a professor and author in the United States.
He was part of the white supremacist Dunning School of Confederate sympathizing anti-Reconstruction Southern scholars during the Jim Crow era.
His book on Reconstruction era Florida, based on his Phd thesis was reissued as part of a series celebrating Florida's quadracenntennial featuring the governor and cabinet on the opening pages.
Other books in the series included Carpetbag Rule in Florida, putatively by John Wallace.
Fletcher M. Green wrote a lengthy introduction to the quadracentenbial edition covering Watson's life, publishings, and criticisms of the Dunning School.
