David Charles Abell (born 1958) is an American conductor of opera, orchestral music and musical theater. Described as "a protean talent" with "impeccable and inspired" skill as a conductor, he is active in symphonic music, opera and musical theatre. Abell was one of Leonard Bernstein's last protégés, and collaborated with Bernstein on many works during the 1980s.

Abell is known for his television appearances worldwide as conductor of the Les Misérables' 10th and 25th Anniversary concerts. He is also recognized as an authoritative interpreter of the musicals of Stephen Sondheim.

In addition to maintaining an active international opera career, Abell has worked to restore clarity to musical scores with poorly preserved source materials. As of 2017, Abell is a resident of London.
