The 2004-05 Deutsche Eishockey Liga season was the 11th season since the founding of the Deutsche Eishockey Liga (German Ice Hockey League). The Eisbären Berlin (Berlin Polar Bears) became first time German Champion, a feat they will repeat a number of times in the next seasons. The Kassel Huskies was allowed to stay in the league, despite losing the play-down, as Grizzly Adams Wolfsburg lost its DEL license.
