Lyn Toppfotball (Norwegian pronunciation: [lyːn]) is a Norwegian football club and a department of the sports club Ski- og Fotballklubben Lyn based in Oslo, whose members also participate in Nordic skiing and orienteering. Until 2010, SFK Lyn had two football departments, one professional section and one amateur section. After the professional football department, FK Lyn was bankrupted in 2010, the fans decided to support the amateur department, Lyn Fotball, instead. With the help of some of the old FK Lyn players, Lyn Fotball have won three consecutive promotions, and is playing in the Third Division. The team plays its home matches at Bislett Stadium, and the head coach is Finn Bredo Olsen.
