The 1999–2000 Deutsche Eishockey Liga season was the 6th season of the Deutsche Eishockey Liga (English: German Ice Hockey League). An agreement was reached between DEL and the 1. Liga. With DEL being the top-level league, it would be known as the DEL - Die 1. Bundesliga, and the 1. Liga as the 2. Bundesliga. A new logo displaying the full name was introduced at the same time. The regular season was played from September 10, 1999 until March 12, 2000; the playoffs started soon thereafter on March 17. The München Barons, who bought their license from the EV Landshut, became DEL champions.
