Shaun William George Ryder (born 23 August 1962) is an English singer. As the lead singer of Happy Mondays, he was a leading figure in the Madchester cultural scene during the late 1980s and early 1990s. In 1993, he formed Black Grape with former Happy Mondays dancer Bez. He was the runner-up on the tenth series of I'm a Celebrity...Get Me Out of Here!. Ryder collaborated with Gorillaz on "Dare", which peaked at number one on the UK Singles Chart in September 2005, becoming the band's only UK number one single. Ryder is known for his distinctive sprechgesang and lyricism.

Shaun William George Ryder was born on 23 August 1962 in Little Hulton, Lancashire, the son of nurse Linda and postman Derek (who would later become Happy Mondays's tour manager). By the age of 13, he had left school to work on a building site.

Happy Mondays' first release was the "Forty Five EP", often called the "Delightful EP" after its first track. It was released on Factory Records in September 1985. Their first album, Squirrel and G-Man Twenty Four Hour Party People Plastic Face Carnt Smile (White Out), was released in 1987 and was produced by John Cale. This was followed by two further albums: Bummed, in 1988, produced by Martin Hannett, and Pills 'n' Thrills and Bellyaches, in 1990, produced by Paul Oakenfold and Steve Osborne. The latter, recorded at Capitol Studios in Los Angeles, went platinum in the UK, selling more than 350,000 copies. Singles "Step On" and "Kinky Afro" from this album both reached number 5 in the UK singles chart.

By the late 1980s, the Happy Mondays were an important part of the Manchester music scene and personified rave culture. Numerous world tours meant the band had international success as well as massive success in their home country. The line-up of the band during this first and most important ten-year phase never changed, and the six original members Shaun Ryder, Paul Ryder (Shaun's younger brother), Gary Whelan, Paul Davis, Mark Day, and Mark "Bez" Berry remained a tight unit until the first incarnation came to an end in 1994. The band headlined the Friday night at Glastonbury Festival 1990. In November of that year, Paul McCartney commented in NME: "I saw the Happy Mondays on TV, and they reminded me of the Beatles in their 'Strawberry Fields' phase."

Musically, the band fused indie pop guitars with a rhythmic style that owed much to house music, Krautrock, funk, and northern soul. Much of their music was remixed by popular DJs, emphasising the dance influences even further. In style and dress, they crossed hippy fashion and ideals with 1970s glamour. Sartorially and musically, the band helped to encourage the psychedelic revival associated with acid house.^{[citation needed]}

Ryder's early years as a singer for Happy Mondays were depicted in the 2002 British biographical comedy drama film 24 Hour Party People, a semi-fictional account of Factory Records and the Manchester music scene of the 1980s and early 1990s. In the film, Ryder is portrayed by Danny Cunningham.

Ryder has taken part in two reformations of Happy Mondays (1999–2000 and 2004–present). He also released a solo studio album, Amateur Night in the Big Top, in 2003.

In 2000, following the Big Day Out Festival in Australia with Happy Mondays, Ryder stayed on in Perth, Western Australia with Pete Carroll, who had a record label called Offworld Sounds. While in Perth he recorded Amateur Night in the Big Top, an album of punk electronica with Carroll, Shane Norton, Stephen Mallinder from Cabaret Voltaire and Lucky Oceans from American country band Asleep at the Wheel. Uncut called it, "exhilarating stuff. Another wildly implausible Ryder comeback" while Ministry of Sound said it was "A remarkable album. The most vitriolic lyrics this side of [Bob] Dylan's 'Ballad of a Thin Man' and Sex Pistols 'EMI'". The album was recorded quickly during a few late night sessions in Carroll's garage studio during an extremely hot Perth summer. The album was subsequently released on Offworld Sounds.
