The 2008 AFC Champions League was the 27th AFC Champions League, the top-level Asian club football tournament, and the 6th under the current AFC Champions League title. It was the last AFC Champions League before the competition expanded to 32 teams.
Gamba Osaka defeated Adelaide United 5–0 on aggregate in the final to win their first AFC Champions League title. Both clubs qualified for the 2008 FIFA Club World Cup: Gamba Osaka as the AFC representative, and Adelaide United as the host nation's representative, since Japan's spot was reallocated due to Gamba Osaka's qualification as continental champion.
Urawa Red Diamonds were the defending champions, but were eliminated by the eventual winners Gamba Osaka in the semi-finals.
