The Final Frontier is the fifteenth studio album by British heavy metal band Iron Maiden, released on 13 August 2010 in Germany, Austria and Finland, 17 August in North America, 18 August in Japan, and 16 August worldwide. At 76 minutes and 34 seconds, it is the band's second-longest studio album to date, a duration surpassed only by 2015's The Book of Souls. Melvyn Grant, a long-time contributor to the band's artwork, created the cover art.
The album received largely favourable reviews from critics and peaked at No. 1 in 28 countries. This included the United Kingdom, where it became the band's fourth release to top the UK Albums Chart following 1982's The Number of the Beast, 1988's Seventh Son of a Seventh Son and 1992's Fear of the Dark. On top of this, The Final Frontier also charted at No. 4 in the United States, marking their highest placement on the Billboard 200, in addition to gaining the band their first Grammy Award in the Best Metal Performance category for the song "El Dorado", released as a free download on 8 June 2010.
EMI released the album in most of the world, while in the United States it was released jointly by Universal Music Enterprises and Sony Music Entertainment – the successor to the Sanctuary Records/Columbia Records joint venture that had previously controlled the Iron Maiden catalogue in North America.
