Radiator is the second studio album by Welsh alternative rock band Super Furry Animals. It was released in August 1997 by Creation Records, and later the same year in the United States under Flydaddy Records. It peaked at number eight on the UK Albums Chart. In 2005, it was reissued with a bonus disc of other tracks from the time.

Singer Gruff Rhys has described Radiator as "more interesting" than the band's debut Fuzzy Logic with the group taking advantage of producer Gorwel Owen's "Atari computers, and banks of old vintage synths" to create an album which was "musically ... much more adventurous". In 2013, NME ranked it at number 92 in its list of the 500 Greatest Albums of All Time. The Radiator campaign also marked the first time the band worked with graphic artist Pete Fowler, who provided paintings for the album and accompanying singles' sleeve. The band felt working with Fowler had provided them with a distinct visual identity, and apart from Hey Venus! have collaborated together on each album since.
