Righteous but Ruthless is the second album by the American rapper King Sun, released in 1990. The first two singles were "Be Black" and "Undercover Lover". Many of the tracks met resistance from Black and urban radio stations due to their religious and political content. Righteous but Ruthless peaked at No. 54 on Billboard's Top R&B Albums chart. King Sun supported the album with live dates that included Terminator X and Redhead Kingpin. Righteous but Ruthless was King Sun's final album with Profile Records, as he felt that the label did not promote it.
