Michael Trimble (sometimes spelled Michael Trimbel) (March 15, 1938, Texarkana, Texas) is an American operatic tenor, voice teacher, and writer on music. He had an active international career singing leading roles with opera houses during the 1960s and 1970s. His singing career was cut short due to health concerns, and he has since had an active career as a voice teacher both privately and at the Cleveland Institute of Music, the University of Texas at Austin, and the Aspen Music Festival and School. Several of his students have had successful international opera careers, including Metropolitan Opera star Tonio di Paolo and soprano Beverly Hoch.
