2003–04 DEL season
The 2003–04 Deutsche Eishockey Liga season was the 10th season since the founding of the Deutsche Eishockey Liga. The Frankfurt Lions became German Champions, and the Wölfe Freiburg were relegated back to the 2. Bundesliga after a single season.
A visible change for the fans was the league corporate sponsorship by the German Yellow Pages who signed a 3-year agreement, later extended ending 2009.
