"Just a Friend" is a song written,[3][4] produced[4] and performed by American hip hop artist Biz Markie.

[10] The music video, directed by Lionel C. Martin, acts out the lyrics humorously and includes a scene of Biz Markie singing the chorus dressed as Mozart in 18th-century clothing with a powdered wig in a candlelit room while playing the piano.

[14] In 2006, American rock band Tally Hall recorded a cover of "Just a Friend", later releasing it on streaming platforms in 2019.

[15] In 2007, Chris Rock and Kerry Washington sang "Just A Friend" in a scene from the movie I Think I Love My Wife.
