Hector Dufranne (25 October 1870 – 4 May 1951) was a Belgian operatic bass-baritone who enjoyed a long career that took him to opera houses throughout Europe and the United States for more than four decades. Admired for both his singing and his acting, Dufranne appeared in a large number of world premieres, most notably the role Golaud in the original Opéra-Comique production of Claude Debussy's Pelléas et Mélisande at the Salle Favart in Paris in 1902, which he went on to sing 120 times at that house. He had an excellent singing technique which maintained the quality of his voice even into the latter part of his career. His wide vocal range and rich resonant voice enabled him to sing a variety of roles which encompassed French, German, and Italian opera.
