The 2011 King Cup of Champions, or The Custodian of the Two Holy Mosques Cup, was the 36th season of King Cup of Champions since its establishment in 1957, and the 4th under the current edition.
The tournament was won by Al-Ahli, who beat defending champions Al-Ittihad 4–2 on penalties in the final. It was their first title in current edition and eleventh title overall, they also qualified for 2012 AFC Champions League.
The SAFF Disciplinary Committee decided to award the quarter-final first leg to Al-Ahli against Al-Shabab as a 3–0 forfeit win after Al-Shabab were found guilty of fielding an ineligible player. The game originally ended 2–1 to Al-Shabab.[2]
