Stabaek

After years of lean seasons, they won their first title in 1998 as they emerged victorious in the Norwegian Cup, beating Rosenborg BK 3–1 in the final. After having been relegated to 1. divisjon after a poor 2004 season, they experienced a successful period under new manager Jan Jönsson, during which they returned to the league in 2005, won the 2008 Tippeligaen, their first, and reached the final of the Norwegian Cup, culminating in a very successful 2008 season for the club. Stabæk subsequently won the 2009 Norwegian Super Cup but finished a disappointing 12th and 10th place in the 2010 and 2011 league seasons, respectively, thus narrowly avoiding relegation both times.

Stabæk holds longstanding rivalries with Bærum SK, FK Lyn and Vålerenga, both in the league and by geographical location. The team’s home colors, entirely blue, have earned them the nickname “De Blaa” (The Blue Ones). In 2009, Stabæk became the first Norwegian association football club with both their men's and women’s teams in the premier divisions. Lillestrøm followed suit the next year.

On 30 November 2015, Billy McKinlay was appointed as manager of the club on a two-year contract. McKinlay resigned as manager on 8 July 2016, after being knocked out of the UEFA Europa League by Welsh club Connah's Quay Nomads.

In the 2021 Eliteserien season, Stabæk finished in 15th place, resulting in relegation to the Norwegian First Division for the first time since 2012.
