The World Contamination Tour was a concert tour supporting My Chemical Romance's fourth album Danger Days: The True Lives of the Fabulous Killjoys. This was the first tour My Chemical Romance had done since the departure of their drummer Bob Bryar. For the tour, Michael Pedicone was the stand-in drummer.

Danger Days: The True Lives of the Fabulous Killjoys is the fourth studio album by the American rock band My Chemical Romance, released on November 22, 2010 by Reprise Records. Its songs are associated with the band's well known sound of alternative rock, pop-punk, and punk rock, along with an introduction of new musical elements, including power pop, pop rock, and electronic rock. The primary musical inspiration for the album came from contemporary rock, psychedelic rock, and protopunk bands of the sixties and seventies. It was the penultimate album released by the band before their six-year disbandment from 2013 to 2019.
