Pierre-Eustache Daniel Fignolé (1913–1986) was a Haitian politician who became Haiti's provisional head of state for three weeks in 1957. He was one of the most influential leaders in the pre-Duvalier era, a liberal labor organizer in Port-au-Prince so popular among urban workers that he could call upon them at a moment's notice to hold mass protests, known as "woulo konpresè"—Haitian Creole for "steamroller."
