The 2005 Tippeligaen season began on April 10, 2005, and was concluded with the last of 26 rounds played on October 29. 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 runner-ups (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.
Number thirteen (Aalesund) and fourteen (Bodø/Glimt) were relegated, while number twelve (Molde) had to play two qualification matches (home and away) against number three (Moss) in Adeccoligaen (where number one and two are directly promoted) for the last spot in next year's season. Molde won the qualification matches.
The greatest surprises of the 2005 season were the great performance of Start, promoted to the Tippeligaen in the 2004 season and ended up winning silver, and the disappointing performance of Rosenborg which fought against relegation from the Premier League after winning it for 13 straight seasons.
1,726,145 people attended the matches, and that's a new record for the Tippeligaen. It is 300,000 more than the previous year. It is also more than twice as much as in 1995, when only 841,717 attended the matches during the whole season.
