Skiklubben Ull was a Norwegian Nordic skiing club based in Oslo. Founded in 1883, Skiklubben Ull attracted several skilled sportsmen who between 1883 and 1891 won six Ladies' Cups and one King's Cup in national skiing events. The sporting facilities belonging the club were located in Vestre Aker, with the ski jumping hill Ullbakken near Frognerseteren being opened in 1884. The prestigious Husebyrennet was staged there once. Members of SK Ull were later instrumental in moving this prestigious contest to the hill Holmenkollbakken.
