Haircut One Hundred (also known as Haircut 100) was a pop music band, formed in 1980 by Nick Heyward, Les Nemes, Graham Jones, Phil Smith, Mark Fox, and Blair Cunningham.

They were successful from the beginning, with their 1981 single Favourite Shirts (Boy Meets Girl) setting the stage for the breakthrough success of the album Pelican West (1982). The single Love Plus One was even bigger than anything previous, and Haircut 100 seemed poised for stardom just as Heyward decided to seek a solo career. The remainder of the band tried to continue with the album Paint and Paint (1984, with percussionist Mark Fox taking over Heyward's vocal duties), but they broke up soon after.

Although somewhat dismissed as a one hit wonder, the band proved influential by the late '00s when bands such as Vampire Weekend and No Kids emerged employing a similar style of preppy, afrobeat‑driven guitar pop.
