Ullern Idrettsforening is a Norwegian multi-sports club from Ullern, Oslo. It has sections for association football, team handball, basketball, bandy and cheerleading. The club colors are white and red.
General history 
The club was founded in 1971 as a merger of the multi-sports club Liull, the multi-sports club Bestum IF (founded 1914), the gymnastics club Lilleaker TF and Ullern Basket (founded 1956). Liull was in turn a merger of the skiing club Ullern SK (founded 1909) and Lilleaker IF (founded 1913). The club counts 1909 as its founding year.
Lilleaker IF had been named Fagforeningenes IL, Lysaker from 1913 to 1924. That year, the Workers' Sports Federation was founded, but membership for Lilleaker IF here was voted down. As a result, the splinter club Fagforeningenes IL, Lilleaker was established. LIF and Fagen were reunited again in 1936, on the condition that the membership in the Workers' Sports Federation was retained. This federation was discontinued after the Second World War, as the club was also merged with Ullern SK to Liull (a portmanteau of the two names).
Lilleaker TF was originally the women's section of Fagen, founded on 3 October 1929. Following the merger in 1936, the gymnastics section broke away in 1938 to found the gymnastics club Najaden. It was too a member of the Worker's Sports Federation. The club was then renamed Lilleaker TF in 1945, and became a part of the large merger in 1971.
