Eldorado is the fourth studio album by the Electric Light Orchestra (ELO). It was released in the United States in September 1974 by United Artists Records and in the United Kingdom in October 1974 by Warner Bros. Records.

The Electric Light Orchestra (ELO) are an English rock band formed in Birmingham in 1970 by songwriters and multi-instrumentalists Jeff Lynne and Roy Wood with drummer Bev Bevan. Their music is characterised by a fusion of pop and classical arrangements with futuristic iconography. After Wood's departure in 1972, Lynne became the band's sole leader, arranging and producing every album while writing nearly all of their original material. From this point until their first break-up in 1986, Lynne, Bevan, and keyboardist Richard Tandy were the group's only consistent members.
