Jason D. Harrow (born May 12, 1976), better known by his stage name Kardinal Offishall ( /kɑrdɨˈnæl oʊfɨˈʃæl/), is a Canadian rapper and record producer. He is often credited as Canada's "hip-hop ambassador", and is best known for his distinctive reggae and dancehall-influenced style of hip-hop.

In 1997, Kardinal released his debut album, Eye & I, on independent label Capitol Hill Music, to critical acclaim. In 2000, he released the EP, Husslin', also independently on Figure IV Entertainment, which helped establish him as one of Canada's best hip-hop producers. The same year, Kardinal signed with major label MCA Records, and released his second album Quest for Fire: Firestarter, Vol. 1 in 2001. The lead single, "BaKardi Slang", became his first single to appear on a U.S. Billboard chart. After releasing the single "Belly Dancer" in 2003, he left MCA Records after it was absorbed by Geffen Records.

In 2005, Kardinal released his third album, Fire and Glory, on the Canadian division of Virgin Records. The single "Everyday (Rudebwoy)" became a top twenty hit in Canada. In 2008, his fourth album Not 4 Sale was released on Kon Live Distribution, a subsidiary of Geffen Records. The album was a critical success, spawning the hit single "Dangerous". The single was his first to chart on the Billboard Hot 100, peaking at number five. Kardinal will release his fifth album—his second under Kon Live Distribution—Mr. International in 2012.
