Rosemary Glyde (September 15, 1948 — January 18, 1994) was an American violist and composer. Focusing on expanding the limited repertory for solo viola, she wrote and transcribed many works for that instrument, including Sergei Rachmaninoff's Cello Sonata and Johann Sebastian Bach's Cello Suites for viola. She founded the New York Viola Society in 1992. Glyde died on January 18, 1994 due to cancer in Mount Kisco, New York. The New York Viola Society awards a "Rosemary Glyde Scholarship" to students for viola study in her honor.
