The U2 360° Tour was a worldwide concert tour by rock band U2. Launched in support of the group's 2009 album No Line on the Horizon, the tour visited stadiums from 2009 through 2011. It was named for a stage configuration that allowed the audience to almost completely surround the stage. To accommodate this, a massive four-legged structure nicknamed "The Claw" was built above the stage, with the sound system and a cylindrical, expanding video screen on top of it.

Comprising three legs and 110 shows, the tour began on 30 June 2009 in Barcelona, Spain and concluded on 30 July 2011 in Moncton, Canada. It twice visited Europe and North America, while making stops in South America, Africa, and Oceania. The tour was generally well received by critics and fans. By its conclusion, U2 360° had set records for the highest-grossing concert tour with $736 million in ticket sales, and for the highest-attended tour with over 7.2 million tickets sold.
