Street King Immortal was a planned studio album by American rapper 50 Cent.

Curtis James Jackson III, known professionally as 50 Cent, is an American rapper, actor, television producer, and businessman. Born in South Jamaica, a neighborhood of Queens, Jackson began pursuing a musical career in 1996. In 1999-2000, he recorded his "debut" album Power of the Dollar for Columbia Records, however he was struck by nine bullets during a shooting in May 2000, causing its release to be cancelled and Jackson to be dropped from the label. His 2002 mixtape, Guess Who's Back? was discovered by Detroit rapper Eminem, who signed Jackson to his label Shady Records, an imprint of Dr. Dre's Aftermath Entertainment and Interscope Records that same year.
