"El Dorado" is the second track from English heavy metal band Iron Maiden's 2010 album The Final Frontier.

The song was released as a free download on the band's official site at 00:01 on 8 June 2010 (UTC), one day before the album's supporting tour began.

Regarding the early online release of the song, vocalist Bruce Dickinson explained, "El Dorado is a preview of the forthcoming studio album.

"[2] Dickinson explained that the lyrics are a cynical critique of the financial crisis of 2007–08, comparing the bankers responsible with the people who sold the myth of El Dorado:[1] [El Dorado] has a cynical lyric about the economic crap that's been happening.

[4][5] The song's guitar solo, which lasts from about 3:42 to 4:23, is a trade-off divided into three parts; the first is played by Adrian Smith (3:42–3:53), the second by Dave Murray (3:53–4:06), and the third, which segues into the verse riff again, by Janick Gers (4:06–4:23).
