The Battle of Oslo (Norwegian: Kampen om Oslo) or the Oslo Derby is the name given to football matches between Lyn Fotball and Vålerenga Fotball, both of them from Oslo, the capital of Norway.
The league match at Ullevaal stadion in April 2024 notably broke the attendance record for the Norwegian First Division. The standing record was 17,284, a number that was surpassed by pre-match ticket sales already two weeks ahead of the match. The figure ended at 25,103, far exceeding the former record.
