Latin hip hop or Latin rap is hip hop music recorded by artists of Latin American and Iberian (Spain and Portugal) origin. 

In the late 1980s and early 1990s, most Latin rap came from the West Coast of the United States. Cuban-American artist Mellow Man Ace was the first Latino artist to have a major bilingual single attached to his 1989 debut. Mellow Man, referred to as the "Godfather of Latin rap" and a Hip Hop Hall of Fame inductee, brought mainstream attention to Spanglish rhyming with his 1989 platinum single "Mentirosa". In 1990, fellow West Coast artist Kid Frost further brought Latinos to the rap forefront with his single "La Raza." In 1991, Kid Frost, Mellow Man, A.L.T. and several other Latin rappers formed the rap super group Latin Alliance and released a self-titled album which featured the hit "Lowrider (On the Boulevard)". A.L.T. also scored a hit later that year with his remake of the song Tequila. Cypress Hill, of which Mellow Man Ace was a member before going solo, would become the first Latino rap group to reach platinum status in 1991. The group has since continued to release other gold and platinum albums. Ecuadorian born rapper Gerardo received heavy rotation on video and radio for his single "Rico, Suave". While commercially watered-down, his album enjoyed a status of being one of the first mainstream Spanglish CDs on the market. Johnny J was a multi-platinum songwriter, music producer, and rapper who was perhaps best known for his production on Tupac Shakur's albums All Eyez on Me and Me Against the World. He also produced the 1990 single Knockin' Boots for his classmate Candyman's album "Ain't No Shame in My Game", which eventually went platinum thanks to the single.
