Richard Hugh Grove (21 July 1955 – 25 June 2020) was a British historian, environmental activist, and one of the contemporary founders of environmental history as an academic field. His prizewinning book, Green Imperialism: Colonial Expansion, Tropical Island Edens and the Origins of Environmentalism 1600–1860 (1995), was considered a pioneering account of colonial environmental impacts and an origin for early western ideas on environmentalism.
