The Laurence Olivier Award for Best Performance in a Supporting Role in a Musical was an annual award presented by the Society of London Theatre in recognition of achievements in commercial London theatre. The awards were established as the Society of West End Theatre Awards in 1976, and renamed in 1984 in honour of English actor and director Laurence Olivier. This commingled actor/actress award was introduced in 1991, presented through to 2014, then in 2015 was replaced by newly created awards for Best Actor in a Supporting Role in a Musical and Best Actress in a Supporting Role in a Musical. On the 24 occasions that this commingled actor/actress award was given, it was presented 13 times to an actress, 10 times to an actor, and once to "The Chorus".
