The WhatsOnStage Awards, founded in 2001 as the Theatregoers' Choice Awards, are a fan-driven set of awards organised by the theatre website WhatsOnStage.com, based on a popular vote recognising performers and productions of English theatre, with an emphasis on London's West End theatre.

The 2020 WhatsOnStage Awards, the 20th, took place on Sunday, 1 March 2020 at the Prince of Wales Theatre.

It was hosted by theatre star Jodie Prenger and Tom Read Wilson and featured performances from all five nominees for Best New Musical, as well as the cast of The Color Purple.
