Hip hop music in Washington, D.C. has been an important part of the culture of the area.
 The traditional style of hip hop in the city has been described as not quite the same as New York City hip hop and not quite the same as Southern hip hop.
 Rather, it has been influenced by both regions to form its own unique style of music.
 The population of D.C. is not large enough to support as many distinct subgenres of rap as other metropolitan areas, and as a result, the sound and style of D.C. hip hop is very mixed and blended.
 Prominent D.C. based hip hop artists include Wale, Oddisee, Fat Trel, Shy Glizzy, Lightshow, Ant Glizzy, Percy Jonez & Santino Ranks of YNWV and a few newcomers , GoldLink, Chaz French & Jay IDK.
 Many of these newcomers are typically featured on local radio stations such as 93.9 WKYS.

New Zealand hip hop derives from the wider hip hop cultural movement originating amongst African Americans in the United States.
 Like the parent movement, New Zealand hip hop consists of four parts: rapping, DJing, graffiti art and breakdancing.
 The first element of hip hop to reach New Zealand was breakdancing, which gained notoriety after the release of the 1979 movie "The Warriors".
 The first hip hop hit single, "Rapper's Delight" by the Sugarhill Gang, became a hit in New Zealand when it was released there in 1980, a year after it was released in the United States.
 By the middle of the 1980s, breakdancing and graffiti art were established in urban areas like Wellington and Christchurch.
 By the early 1990s hip hop became a part of mainstream New Zealand culture.
