Roland Wiltse Hayes (June 3, 1887 – January 1, 1977) was an American lyric tenor and composer. Critics lauded his abilities and linguistic skills demonstrated with songs in French, German, and Italian. Hayes' predecessors as well-known African-American concert artists, including Sissieretta Jones and Marie Selika, were not recorded. Along with Marian Anderson and Paul Robeson, Hayes was one of the first to break this barrier in the classical repertoire when he recorded with Columbia in 1939.
