Guess Who's Back? is a debut official mixtape by American rapper 50 Cent, released April 26, 2002 on independent label Full Clip Records in the United States. It is his first official release after his 2000 effort Power of the Dollar went unreleased due to Columbia Records' discovery of a May 2000 shooting where 50 Cent was struck by nine bullets, and was subsequently dropped from the label as a result. The album features production by Trackmasters, DJ Clark Kent, Father Shaheed, Sha Money XL, Red Spyda, and Terence Dudley. Guess Who's Back? received generally positive reviews from music critics and peaked at number 28 on the U. S. Billboard 200 chart.
