Robert Thurston ("Bob") Dart (3 September 1921 – 6 March 1971) was an English musicologist, conductor and keyboard player. He was one of Britain's leading musicologists of the post-World War II generation. From 1964 until his death he was King Edward Professor of Music at the University of London, based at King's College London. A continuo player, he made numerous appearances on the harpsichord; he was also a conductor. He performed with the Boyd Neel Orchestra, and when in 1955 Neel moved to Canada, he became its artistic director. The ensemble, renamed Philomusica of London, performed works from Dart's own editions. Dart made many harpsichord, clavichord and organ recordings, especially for the L'Oiseau-Lyre label.
