Geoffrey Howard Eley (born 4 May 1949) is a British-born historian of Germany. He studied History at the Balliol College of Oxford University and received his D.Phil from the University of Sussex in 1974. He has taught at the University of Michigan, Ann Arbor in the Department of History since 1979 and the Department of German Studies since 1997. He now serves as the Karl Pohrt Distinguished University Professor of Contemporary History at Michigan. Eley's early work focused on the radical nationalism in Imperial Germany and fascism, but has since grown to include theoretical and methodological reflections on historiography and the history of the political left in Europe.
