Iron Maiden is the debut studio album by English heavy metal band Iron Maiden, released on 14 April 1980 by EMI Records in the UK and Harvest and Capitol Records in the US. The North American version included the song "Sanctuary", released in the UK as a non-album single. In 1998, along with the rest of the band's pre-1995 releases, Iron Maiden was remastered with "Sanctuary" added in all territories. However, 2014 vinyl reissues, 2015 digital releases and 2018 CD reissues use the original track listing across the globe. It is the band's only album to feature guitarist Dennis Stratton.

Iron Maiden are an English heavy metal band formed in Leyton, East London, in 1975 by bassist and primary songwriter Steve Harris. Although fluid in the early years of the band, the line-up for most of the band's history has consisted of Harris, lead vocalist Bruce Dickinson, drummer Nicko McBrain, and guitarists Dave Murray, Adrian Smith and Janick Gers. As pioneers of the new wave of British heavy metal movement, Iron Maiden released a series of UK and US Platinum and Gold albums, including 1980's debut album, 1981's Killers, and 1982's The Number of the Beast – its first album with Bruce Dickinson, who in 1981 replaced Paul Di'Anno as lead singer. The addition of Dickinson was a turning point in their career, establishing them as one of heavy metal's most important bands. The Number of the Beast is among the most popular heavy metal albums of all time, having sold almost 20 million copies worldwide.
