Lorenzo Dechalus (born September 17, 1968), known professionally as Lord Jamar, is an American rapper, DJ, record producer, actor and podcaster. He is a founding member of hip hop group Brand Nubian, which formed in 1989.  Jamar was a frequent guest on VladTV, where he has drawn attention for his comments on social issues such as racism, sexism and homophobia.

Jamar was introduced as a DJ to Grand Puba, who already had celebrity status in New Rochelle. Jamar and Puba began recording demos after Puba saw Jamar rapping in a park. After Puba left a group he was with, he and Jamar recruited Sadat X and decided to form Brand Nubian. The three began working on demos at Jazzy Jay's studio, despite not having enough money to pay for studio time. The first song Brand Nubian made was titled "I Ain't Goin' Out Like That". The group eventually signed to Elektra Records and received an album deal after the release of their single "Feels So Good".

Brand Nubian's debut studio album, One for All, was released in 1990. It received the coveted "five mic" rating from The Source magazine, and is regarded as one of the greatest hip hop albums of all time.  Some time during late 1990 and early 1991, Grand Puba left Brand Nubian. Jamar claims that this was partly due to the fact that he and Puba often clashed due to them both having "alpha" personalities. Jamar had picked up on studio techniques during the production of One for All. Due to Puba's departure, Jamar decided to focus more on production due to people attempting to take advantage of Puba's absence and produce for the group. Jamar then built a studio in Sadat X's basement and began producing. Jamar produced the entirety of the group's second studio album, In God We Trust (1993), while Sadat X helped with finding samples.

After Brand Nubian's third studio album, Everything is Everything (1994), Jamar discovered and began working with Florida-based hip hop group Dead Prez, signing them to Loud Records.

As an actor, Jamar is best known for his role of Supreme Allah on the TV series Oz. He has appeared on Law & Order: Special Victims Unit, Third Watch, and The Sopranos. He has also done production work for artists such as Dead Prez, whom he discovered,[citation needed] Buckshot, Shaka Amazulu the 7th and Tom Browne. He released his debut solo album The 5% Album (an album dedicated to the Nation of Gods and Earths) on June 27, 2006. Like his onscreen character on Oz, Jamar is a member of the Nation of Gods and Earths.

Jamar currently co-hosts a podcast, Yanadameen Godcast, with fellow rapper Rah Digga. He has repeatedly criticized and distanced himself from Black Lives Matter and its activities on his podcast, saying, "It's not our movement," and that, in regard to the George Floyd protests, "most people looting are white; some riots are staged by paid agitators.
