The 2004–05 Crown Prince Cup was the 30th season of the Saudi premier knockout tournament since its establishment in 1957. It started with the qualifying rounds on 8 December 2004 and concluded with the final on 13 May 2005.
Al-Ittihad were the defending champions, but were eliminated in the semi-finals by Al-Hilal.[1]
Al-Hilal won their 5th title following a 2–1 win over Al-Qadisiyah in the final.[2]
The winner of the Crown Prince Cup earns automatic qualification to the 2006 AFC Champions League group stages. However, as Al-Hilal qualified for the AFC Champions League as league winners, Al-Shabab, the league runners-up, took this Champions League spot.
All of the competing teams that are not members of the Premier League competed in the qualifying rounds to secure one of 4 available places in the Round of 16. The qualifying competition began on 8 December 2004. First Division sides Al-Khaleej, Al-Raed, and Najran, and Second Division side Al-Watani qualified.[3]
