Old school hip hop (also spelled “old skool“) describes the earliest commercially recorded hip hop music (approximately from 1979–1984), and the music in the period preceding it from which it was directly descended (see Roots of hip hop). Old school hip hop is said to end around 1983 or 1984 with the emergence of Run–D.M.C., the first new school hip hop group. However, some old school rap stations cover 1980s hip hop in general, occasionally extending even into the mid 1990s.

The image, styles and sounds of the old school were exemplified by figures like Afrika Bambaataa, The Sugarhill Gang, Spoonie Gee, Treacherous Three, Funky Four Plus One, Kurtis Blow, Fab Five Freddy, Busy Bee Starski, Lovebug Starski, Doug E. Fresh, LL Cool J, The Fat Boys, The Cold Crush Brothers and Grandmaster Flash and the Furious Five, and it is characterized by the simpler rapping techniques of the time and the general focus on party related subject matter.
