FK Gjøvik-Lyn is a Norwegian football club based in Gjøvik, which was founded on 1 February 1902 as Sportsklubben Thor.

The club's honours include winning the 1962 Norwegian Cup.

The club had only their football department left and therefore changed its name to Fotballklubben Lyn.

Gjøvik-Lyn won the 1962 Norwegian Cup after Vard was defeated 2–0 in the final at Ullevaal Stadion on 28 October 1962.
