The World Magnetic Tour was a concert tour by the American heavy metal band Metallica in support of the band's ninth studio album, Death Magnetic, which was released on September 12, 2008.

The tour officially kicked off in October 2008 in Glendale, United States, following three European promotional dates in September and two U.S. rehearsal shows. By September 2010, the tour had reached North America, Europe, South America, Asia and Oceania. The tour culminated with three dates in Melbourne, Australia, in late November 2010.

A North American leg, their first since the Madly in Anger with the World Tour in 2004, began in Phoenix, Arizona, and wrapped up in late December in Oakland, California. The leg continued in early January 2009, starting in Milwaukee and finishing up in Newark, New Jersey, in early February.

In February 2009, the band commenced a European tour. The group played three rounds of dates, resuming in late March and then returning again in May. In between the first and second legs, the band performed a small promotional show in Austin, Texas, U.S. to support the video game release Guitar Hero: Metallica. The European legs began in Nottingham, England, and eventually culminated in Cologne, Germany.

In June 2009, the group played three dates in Mexico City. The shows reached a total capacity of 158,349 and were the band's first shows in Mexico in ten years. Later in the month, the group returned to Europe, performing a mixture of indoor and outdoor shows, and festival appearances. The leg featured headline slots at the first iterations of the Sonisphere Festival, a new festival event which took place in Finland, Germany, the Netherlands, Spain, Sweden and the UK. The leg began in Helsinki and finished in early August in Knebworth, England.

In September 2009, the band kicked off a third North American leg, beginning in Nashville, Tennessee, and finishing in mid-November in New York City. The act resumed touring duties in December, performing five dates in the Western U.S.

In January 2010, the band headed to South America, playing mostly outdoor shows. The leg kicked off in Lima and finished in São Paulo, Brazil. In March, the group returned to Mexico, performing in Guadalajara and Monterrey. The leg continued on with additional dates in South America, as well as shows in Central America. The band also performed for the first time in countries such as Puerto Rico, Costa Rica and Guatemala.

In April 2010, the act once again returned to Europe, beginning with two dates in Oslo. The leg included appearances at the 2010 editions of the Sonisphere Festival, which featured exclusive billings of the "Big Four" of thrash metal: Slayer, Megadeth and Anthrax, as well as Metallica. The events took place in Poland, Switzerland, Czech Republic, Bulgaria, Greece, Romania and Turkey. The band also returned to Israel in May, for the third time in their career.
