Heinz Julius Rehfuss (25 May 1917 – 27 June 1988) was a Swiss operatic bass-baritone, who later became an American citizen.
He was particularly associated with the title roles in Don Giovanni and Boris Godunov, and Golaud in Pelléas et Mélisande.
Born in Frankfurt, he was the son of Carl Rehfuss (1885-1946), a baritone, concertist and teacher, and his wife, alto Florentine Rehfuss-Peichert.
He made his debut in 1938 at the Städtebundtheater in Biel-Solothurn, as a choral singer and stage designer, and sang as a soloist in Lucerne during the 1938-39 season.
[citation needed] Rehfuss took part in the premiere of Nono's opera Intolleranza 1960, in 1961.
