During the 2002–03 Dutch Football season, AFC Ajax competed in the Eredivisie.

Despite being the top scorers in the Eredivisie, Ajax were unable to defend their title and finished second. They also failed to retain the cup, but compensated by reaching the Champions League quarter-finals before being knocked out by eventual winners A.C. Milan.
