Theodore Rosengarten (born December 17, 1944) is an American historian. He graduated from Amherst College in 1966 with a BA, and earned his PhD from Harvard University with a dissertation on Ned Cobb (1885–1973), a former Alabama tenant farmer. Subsequently, he developed his interviews with Cobb as a kind of "autobiography", All God's Dangers: The Life of Nate Shaw (1974), which won the U.S. National Book Award in category Contemporary Affairs.
