2004–05 UPC-ligaen season

The 2004–05 UPC-ligaen was the sixty-fifth season of Norway's premier ice hockey league, Eliteserien, which as of this season became known as the UPC-ligaen after UPC had acquired the naming rights for five years. Vålerenga won both the League Championship and the Norwegian Championship, completing their nineteenth "double". A total of ten teams contested the league, including newcomers Comet who competed at the highest level for the first time.

The regular season commenced on 19 September 2004 and concluded on 20 February 2005. Vålerenga clinched their twenty-fifth league title after winning 3–2 in overtime against the Sparta Warriors on 17 February. This left them with an unassailable lead of seven points over the Trondheim Black Panthers, with only one round left to play. The result also confirmed Trondheim as runners-up ahead of the Storhamar Dragons.

The playoffs to determine the 2005 Norwegian Ice Hockey Champions were contested from 22 February to 20 March 2005. Vålerenga were crowned champions for the twenty-third time after defeating Trondheim by 4 games to 1 in the best-of-seven Final.
