Heaven & Hell was a British-American heavy metal supergroup active from 2006 to 2010, featuring guitarist Tony Iommi, bassist Geezer Butler, vocalist Ronnie James Dio and drummer Vinny Appice.

The four members of Heaven & Hell recorded and toured together as Black Sabbath from 1980 to 1982 and from 1991 to 1992. Dio had replaced founding Black Sabbath vocalist Ozzy Osbourne and Appice had replaced founding drummer Bill Ward. The decision to call the group Heaven & Hell was made to differentiate the project from the Osbourne-led Black Sabbath line-up. The name of the group is derived from the 1980 album Heaven and Hell, the first Black Sabbath album to feature Dio as vocalist.

After Heaven & Hell reunited to record three new songs for the 2007 compilation album, Black Sabbath: The Dio Years, they embarked on a 2007–2008 tour. According to Iommi, the name change was made to avoid confusion between the two different line-ups of Black Sabbath, so that fans at concerts "would not expect to hear 'Iron Man' and 'War Pigs' and all that... it's none of the old stuff, it's none of the Ozzy period. It's all Dio stuff. So by calling ourselves Heaven & Hell, it's revisiting that period."

The group released one new studio album in 2009, and disbanded following Dio's death from stomach cancer in 2010.
