Noel Gallagher (born 29 May 1967) is an English musician, best known as the former lead guitarist, backing vocalist and principal songwriter of the English rock band Oasis.

Raised in Burnage, Manchester with brother Liam, Noel began learning guitar at the age of thirteen. After a series of odd jobs in construction, Noel worked for local Manchester band, Inspiral Carpets as a roadie and technician in 1988. Whilst touring with the Inspiral Carpets, he learned that Liam had formed a band of his own, known as The Rain, which eventually took on the name "Oasis". After Noel returned to England, he was invited by Liam to join Oasis as songwriter and guitarist.

Oasis debut album, Definitely Maybe (1994) marked the beginning of the bands rise to fame as head of the Britpop movement. Oasis second album, (Whats the Story) Morning Glory? became a massive commercial smash. However, Britpop soon declined in popularity, and Oasis next three albums failed to revive its popularity, however the bands final two albums Dont Believe the Truth (2005) and Dig Out Your Soul (2008) were hailed as the bands best efforts in over a decade, which found the band renewed success. On 28 August 2009, following an altercation with Liam prior to a gig in Paris, Noel announced his departure from Oasis and on 23 October 2009, he confirmed he would embark on a solo career.

Noels run with Oasis was marked by turbulence, especially during the peak of Britpop, during which Noel was involved in several disputes with Liam, and the brothers fights and wild lifestyles regularly made headlines in British tabloid newspapers. Noel (along with Oasis) also shared a personal rivalry with fellow Britpop band Blur. However, Noel was often regarded as the spear-head of the Britpop movement, and at one point of time, NME termed a number of Britpop bands (including The Boo Radleys, Ocean Colour Scene and Cast) as "Noelrock", citing Gallaghers influence on their success. Many have praised Gallaghers songwriting, with George Martin claiming Noel to be the finest songwriter of his generation.
