Mojo is the twelfth studio album by American rock band Tom Petty and the Heartbreakers, released on June 15, 2010 on CD and June 29 on Blu-ray. It was Petty's first album with the Heartbreakers in eight years. Mojo debuted at No. 2 on the U.S. Billboard 200, selling 125,000 copies in its first week of release. The album was also the band's first full album with bassist Ron Blair since 1981's Hard Promises, as he played on only two tracks on the previous Heartbreakers album, The Last DJ.

Tom Petty and the Heartbreakers were an American rock band from Gainesville, Florida. Formed in 1976, the band originally comprised lead singer and rhythm guitarist Tom Petty, lead guitarist Mike Campbell, keyboardist Benmont Tench, drummer Stan Lynch and bassist Ron Blair. In 1982, Blair, weary of the touring lifestyle, departed the band. His replacement, Howie Epstein, stayed with the band for the next two decades. In 1991, Scott Thurston joined the band as a multi-instrumentalist—mostly on rhythm guitar and second keyboard. In 1994, Steve Ferrone replaced Lynch on drums. Blair returned to the Heartbreakers in 2002, the year before Epstein's death. The band had a long string of hit singles including "Breakdown", "American Girl", "Refugee", "The Waiting", "Learning to Fly", and "Mary Jane's Last Dance", among many others, that stretched over several decades of work.
