New Worlds Fair is a 1975 concept album by UK rock group Michael Moorcock & The Deep Fix.

The single "Dodgem Dude"/"Starcruiser" had been recorded just prior to the album, but United Artists passed on the idea of releasing it.

Some time later as Moorcock was visiting his former manager Douglas Smith, with whom he was in dispute, he discovered the tapes for the single lying around the office.

Without Smith's knowledge he took them, passing them onto Frenchy Gloder, who gave the single a belated release on his Flicknife Records label (FLS200, December 1980).

In 2004, Voiceprint Records released an alternate version of the album as Roller Coaster Holiday.
