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.
Club members also held important positions in the general administration of skiing in Norway. The first Ull chairman Johan Bechholm was also the first secretary of the Association for the Promotion of Skiing; Karl Roll became the first chairman of the Norwegian Ski Federation, Hjalmar Krag became chairman in the Confederation of Sports and Fritz R. Huitfeldt was a pioneer in several respects.
The club was founded by students and its membership later drew from the upper social strata. During the first ten years of club history, forty-four of the sixty members admitted into the club belonged to one of four prestigious professions; physician, military officer, jurist or engineer. The club was furthermore exclusive, in that it only had 119 members during its first 100 years of existence. In 1893 the club raised its own cabin, thus grouping it together with other so-called "cabin ski clubs" such as Christiania SK. SK Ull eventually evolved from a skiing club to a social club in a skiing setting, using the old cabin for member meetings, which were also visited by the King of Norway.
