Lincoln Rafael Díaz-Balart (August 13, 1954 – March 3, 2025) was a prominent Cuban-American attorney and Republican politician who served as a U.S. Representative from Florida from 1993 to 2011. Born in Havana, Cuba, he came from a politically influential family that fled after the 1959 Cuban Revolution. His father, Rafael Díaz-Balart, was a Cuban senator and opponent of Fidel Castro, and his younger brother, Mario Díaz-Balart, also became a U.S. Congressman. Before his congressional career, Díaz-Balart served in the Florida House of Representatives (1986-1992) and briefly in the Florida Senate (1992-1993). As a Cuban exile, he was known for his staunch anti-Castro stance and became a key architect of the Helms-Burton Act in 1996, which tightened U.S. sanctions against Cuba. During his tenure in Congress, he served on the House International Relations Committee and chaired the Congressional Hispanic Leadership Institute. After retiring from Congress in 2011, he established a law practice and consulting firm in Miami, Florida, continuing his work on international affairs and Cuban policy until his death in 2025.
