"Illusions in G Major" is a song recorded by Electric Light Orchestra (ELO) and is track eight on the band's 1974 album Eldorado.

It was used as the B-side to the popular hit "Can't Get It Out of My Head", a 1975 hit in the United States. The song clocks in at 2:37, making it one of the shortest on the album. The theme of the song is about a rock star talking to his psychiatrist about his mysterious visions, he even mentions "I heard the crew a hummin' tunes that sounded like The Rolling Stones and Leonard Cohen", then also "I heard the pilot saying, poems that were written by John Keats and Robert Browning".

Rolling Stone critic Ken Barnes called it a "skillful, power-packed Fifties-style rocker with intriguing lyrics."{{cite magazine|magazine=Rolling Stone|title=Eldorado|date=January 2, 1975|author=Barnes, Ken|url=https://web.archive.org/web/20080216080625/http://www.rollingstone.com/artists/electriclightorchestra/albums/album/122346/review/5944334/eldorado|accessdate=2024-12-11}} Phonograph Record critic Michael Davis said that it "really rocks out."{{cite magazine|magazine=Phonograph Record|author=Davis, Michael|date=November 1974|title=Eldorado}}
