Kjøbenhavns Boldklub or KB is a Danish sports club based in Copenhagen. The club was founded 26 April 1876 on the grassy fields in outer Copenhagen which later became Fælledparken. Tennis has been played since 1883. The club hosted, in 1921, one of the early tennis majors: the World Covered Court Championships, won by William Laurentz that year. Today, along with the sports already mentioned, the club also has facilities for badminton, swimming and pétanque.
The football team went on to become the most successful club in Denmark, winning a record 15 Danish championship titles from 1913 to 1980. In 1991, KB and B 1903 merged their professional football teams and formed F.C. Copenhagen. Until 1 January 2009, the F.C. Copenhagen reserves played under the KB name.
Football was added to the club's programme on 24 October 1878, making it the oldest football club in the world outside of Great Britain. The first advertised games were scheduled for the military exercise ground near Rosenborg Castle on 5 January 1879 (at 11am). It took until 7 September 1879 for a first 'show'-game at Eremitagen in Klampenborg. This makes KB to be the oldest football club on continental Europe.
Since November 2018, KB is a member of the Club of Pioneers.
Danish national football team all-time top scorer Poul Nielsen (1891–1962) played for KB during all of his career.
Legendary striker Preben Elkjær Larsen played for KB for one season as a trainee (1973–1974), while Nicklas Bendtner, who as of 2019 plays for FCK, was a former trainee at KB between the years of 2002 and 2004.
