Borussia Dortmund played the 2002–03 season in the Bundesliga. Aside from failing to retain the Bundesliga title, Dortmund failed to reach the Champions League knockout phase, despite winning away from home against eventual champions Milan. In the end, finishing third in Bundesliga was enough to go into the qualifying phase of the Champions League for the coming season.
