Sir Anthony Carey Lewis (2 March 1915 – 5 June 1983) was an English musicologist, conductor, composer, and music educator. He co-founded and served as the first chief editor of Musica Britannica, producing scholarly editions of British music hitherto unavailable. He published critical editions of operas by Handel, Purcell and John Blow.

After working in the music department of the BBC, Lewis became professor of music at the University of Birmingham (1947–68) and was principal of the Royal Academy of Music in London (1968–82).

As a conductor Lewis played a role in the baroque music revival of the mid 20th century by directing performances of several Handel opera revivals, and making commercial premiere recordings of works from the 17th and 18th centuries.
