The Laurence Olivier Award for Best Sound Design is an annual award presented by the Society of London Theatre in recognition of achievements in professional 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 award was introduced in 2004, 13 years after the 1991 introduction of individual awards for Best Set Design, Best Costume Design and Best Lighting Design.
