2003–04 R.S.C. Anderlecht season

Anderlecht participated in the Belgian First Division.

Anderlecht won the title for the first time in three seasons.

They had held a big lead over their title rivals Club Brugge for some time, but a bad finish from Anderlecht kept the suspense until the 31st matchday, when Club Brugge drew with Mouscron while the team from Brussels also drew (1-1) at Lierse to confirm their title.
