Stephen J. Spingarn (September 1, 1908 – August 6, 1984) was a mid-20th-century American lawyer and civil servant in the Franklin Delano Roosevelt, Harry S. Truman, and (briefly) Dwight D. Eisenhower administrations, including Special Counsel (1949) and Administrative Assistant to Truman (1950) and lastly commissioner on the Federal Trade Commission (1950–1953) during transition to Eisenhower. Writings on the mid-20th-Century often cite his official writings during office; less often, they describe him in text.
