Luther Roderick Campbell, also known as Luke Skyywalker, Uncle Luke and simply Luke, is an American rapper, promoter, record executive, actor, and former leader of the rap group 2 Live Crew. He is known for having helped create the Miami bass genre, for establishing one of the first rap groups and rap labels in Southern hip hop, and his sexually crude call and response lyrics which were unique for the time period. He also starred in a short-lived show on VH1, Luke's Parental Advisory.

Southern hip hop, also known as Southern rap, South Coast hip hop, or dirty south, is a blanket term for a regional genre of American hip hop music that emerged in the Southern United States, especially in Atlanta, New Orleans, Houston, Memphis, and Miami—five cities which constitute the "Southern Network" in rap music.
