The 2006 edition of the J.League Cup, officially the 2006 J.League Yamazaki Nabisco Cup was sponsored by Nabisco. First-round matches were held from March 29 through May 21. Gamba Osaka were exempt from competing in the group stage, due to their entry into the Asian Champions League. They were therefore entered into the quarter-final stage.
The final was on November 3 at the Tokyo National Stadium. The winners were JEF United Ichihara Chiba, beating Kashima Antlers in the final 2–0 to claim its second J.League Cup.
