The Simulation Theory World Tour^[2] was a world concert tour by English rock band Muse, in support of their eighth studio album, Simulation Theory (2018). The tour began in Houston on 22 February 2019 and ended in Lima on 15 October 2019.^[3] Numerous acts appeared as the opening act, including Tom Morello, Walk the Moon, Nothing But Thieves and SWMRS.^[4]

The tour grossed $102 million, with more than 1.3 million tickets sold, based on 55 reported dates.^[1]

Muse – Simulation Theory, a film containing live footage from the shows at The O2 Arena in London from 14–15 September 2019, as well as additional filmed scenes, was released on 17 August 2020 in IMAX cinemas worldwide with a digital download release on 21 August.^[5]

The Simulation Theory World Tour featured a new enhanced experience package that allowed access to an exclusive mixed reality pre-show party, powered by Microsoft. This included three original virtual reality games, inspired by tracks from Simulation Theory. Additional enhanced experience perks included a premium concert ticket, show-specific poster, interactive photo experience with props and memorabilia from the band's latest videos, and more.^[6]

The staging was similar to The Unsustainable Tour of 2013, with a few differences. It consisted of a main stage, two stage wings and a long catwalk to the B-Stage, where certain songs were played from throughout the show. Behind the stage there was a large LED screen displaying various visuals. During the Metal Medley near the end of the show a large inflatable puppet skeleton called "Murph", similar to ones seen in the music video for "The Dark Side", was featured as if it were towering over the stage. The show also featured 14 dancers performing throughout the show during certain songs – some again linking to the music videos for the album.

The show loosely told the story of being caged in simulations with the world battling back and defeating them with the "creator" at the end of the show. This narrative was expanded upon in the Simulation Theory film with additional scenes.
