Frost* are an English neo-prog supergroup, formed in 2004 by Jem Godfrey and members of Arena, Kino, and IQ. Frost* released their first studio album, Milliontown, in 2006, before splitting up. In 2008, Godfrey reformed Frost*, adding Darwin's Radio vocalist and guitarist, Declan Burke, to the lineup, and released their second album, Experiments in Mass Appeal. The band disbanded again in 2011, to reunite later in September, after a brief hiatus.

Frost* released their third studio album Falling Satellites in 2016 and followed up with their fourth album Day and Age in 2021.

Frost* was formed in September 2004, by songwriter, producer and musician Jem Godfrey - better known for his work creating hits for bands including Atomic Kitten - when he made a decision to return to his own musical past writing and playing progressive music, in the band Freefall.

After writing and recording material on his own for several months, and listening to a broad selection of contemporary progressive music, Godfrey first approached John Mitchell of Arena, The Urbane and Kino, (and currently lead guitarist and singer for It Bites). Mitchell then introduced Godfrey to John Jowitt (also of Arena, and additionally IQ and Jadis), subsequently leading to meeting Andy Edwards (ex Robert Plant and IQ). John Boyes, Godfrey's former band-mate in Freefall in the 1990s, and from the band Rook, had already performed significant rhythm guitar work on the early recordings. With the lineup in place, recording of the first album was completed during winter 2005.

When asked in an interview why there is an asterisk next to the band name, Godfrey replied "That is a serving suggestion; if you get to put it on it means 'serve chilled'! or 'may contain nuts'!"

Frost*'s first album was named after the 26 minute long final track, which was inspired by the book The Apprentice by Gordon Houghton. The album was released in the United States on 18 July 2006 and in Europe on 24 July. The band went on a brief tour to play a selection from the album, supporting Pallas on a four date tour of the Netherlands and Germany in October 2006.

Shortly after returning from the tour, Godfrey announced on the band's blog on MySpace and reiterated by InsideOut in a bulletin on the same site two days later (expired) - that due to his increasing professional and personal commitments elsewhere, Frost* would be dissolved after fulfilling four remaining concert dates. It later emerged that an appearance at the Rites of Spring festival (RoSfest) in 2007, in America, the final scheduled date, had been cancelled. The final appearance of Frost* for the time being, in support of their album Milliontown, was back-up for The Flower Kings at The Scala in Kings Cross, London, on 10 December 2006.

However, in early 2007, Godfrey revived the band name and wrote in his blog about writing material for a second album. Following the band's reformation, Godfrey recruited Declan Burke of Darwin's Radio to contribute vocals and guitars on the follow-up album, Experiments in Mass Appeal which was released worldwide on 17 November 2008. Throughout 2008 Godfrey posted several videos on YouTube called "Frost* Reports," under the user name Planetfrost. In between the recording in early 2008, Frost* supported Spock's Beard for a small tour.
