Glee Live! In Concert! is the debut concert tour by the cast of the FOX television series Glee in 2010 and 2011.
Plans for a Glee tour was first announced in September 2009, described by series creator Ryan Murphy as an additional revenue stream for Fox. The tour was officially confirmed by Fox on March 1, 2010, when Murphy stated: "The response of the fans to our little show has been so immediate and so gratifying, we wanted to get out and thank them live and in person. And what show lends itself more to a concert than Glee?." Series star Lea Michele commented: "This has been such an extraordinary year for Glee and I can't think of a better way to finish up the first season than performing live on stage with the cast."
In June–July 2011, Glee Live had its first UK and Ireland tour, including two dates at London's O2 Arena. A movie of this tour was released in August: Glee: The 3D Concert Movie.
