The Drama Desk Award for Outstanding Actress in a Musical is an annual award presented by Drama Desk in recognition of achievements in the theatre among Broadway, Off Broadway and Off-Off Broadway productions. The awards were established in 1955, with acting awards being given without making distinctions between roles in plays and musicals, or actors and actresses. The new award categories were later created in the 1975 ceremony.
