Robert John Wilson Douglas (1920–1979) was a Canadian geologist who made contributions in the fields of structure stratigraphy, sedimentation, and petroleum geology.
Douglas was awarded a Manly B. Baker Scholarship and graduated from Queen's University in geology and mineralogy. He obtained a Ph.D. degree in geology from Columbia University.
Douglas worked as a student assistant for the Geological Survey of Canada. He left the Survey for three years to serve as a navigator with the Royal Canadian Air Force.
Douglas has contributed to our understanding of the structure of the Canadian Rocky Mountains and northern Canada. His exposition of the mechanics of bedding plane thrusts, of back-limb thrust faults and folding of the thrusts forms the basis for the later work carried out in these areas.
Douglas also studied the stratigraphy of the Mississippian system in southern Alberta. These studies provided a detailed description and classification of carbonate rocks and theories on the formation of oil and gas reservoirs.
Douglas and his wife Winnifred lived in Ottawa, Ontario with their three children, Isabel, Robert and Gordon. He died of a heart attack in 1979.
