Richard Griffin, better known by his stage name Professor Griff, is an American rapper, spoken word artist, and lecturer currently residing in Atlanta. He was a member of the hip hop group Public Enemy, serving as the group's Minister of Information.

Public Enemy is an American hip hop group formed by Chuck D and Flavor Flav on Long Island, New York, in 1985. The group rose to prominence for their political messages including subjects such as American racism and the American media. Their debut album, Yo! Bum Rush the Show, was released in 1987 to critical acclaim, and their second album, It Takes a Nation of Millions to Hold Us Back (1988), was the first hip hop album to top The Village Voice's Pazz & Jop critics' poll. Their next three albums, Fear of a Black Planet (1990), Apocalypse 91... The Enemy Strikes Black (1991) and Muse Sick-n-Hour Mess Age (1994), were also well received. The group has since released twelve more studio albums, including the soundtrack to the 1998 sports-drama film He Got Game and a collaborative album with Paris, Rebirth of a Nation (2006).
