What is the name of Justin Bieber's first concert tour?

Justin Bieber’s first concert tour was the My World Tour. It was his debut headlining tour and supported both his early releases, My World and My World 2.0.

The tour began on June 23, 2010, after Bieber’s breakthrough as a teenage pop star. My World, released in 2009, had established him with songs such as “One Time” and “One Less Lonely Girl,” while My World 2.0 followed in 2010 with the international hit “Baby.”

The My World Tour ran through October 19, 2011, and included eight legs and 126 shows across North America, Europe, Asia, Oceania and South America. Supporting acts included Sean Kingston, Jessica Jarrell, Mindless Behavior and The Stunners on various dates.

The title is sometimes confused with Bieber’s later tours. The Believe Tour followed in 2012–2013, while the Purpose World Tour supported his 2015 album Purpose. “Changes Tour” refers to a much later tour connected with his 2020 album Changes, so none of those names describes his first concert tour.
