2005 Tippeligaen

The 2005 Tippeligaen was the 61st completed season of top division football in Norway. The season began on 10 April 2005, and was concluded with the last of 26 rounds played on 29 October. 3 points were given for wins and 1 for draws.

Vålerenga, the winner of this year's season entered the second round of next year's Champions League qualification, while the runners-up (Start), number 3 (Lyn) and the Norwegian Cup winners enter the UEFA Cup qualification round. The top four teams qualified for the 2004–05 Royal League.

1,726,145 people attended the matches, a new record for the Tippeligaen and 300,000 more than the previous year. It is also more than twice as many as in 1995, when only 841,717 attended the matches during the whole season. The 2005 season was, as of 2019, the last season where all the teams in the division played on natural turfs only.
