Knattspyrnufélag Reykjavíkur, often known by the simplified names of KR Reykjavík or KR, was established in February 1899. They are the oldest football club in Iceland and the most successful in the history of the country's football league. The club's home kit consists of black and white stripes, with Newcastle United serving as the original inspiration for the strip.
For almost a decade, KR were the only functional club in the country, but other teams were soon founded and plans were made for competitive competitions. In 1912, the inaugural Úrvalsdeild title was contested, with KR defeating Fram Reykjavík in a playoff to claim the championship.
Since that time, KR Reykjavík have gone on to win a total of 26 Icelandic league titles; more than any other team in the country. In addition, they have lifted the Icelandic Cup 13 times, which is also a record haul. Further silverware has come in the form of the Icelandic League Cup, which they have lifted 5 times, the Icelandic Super Cup, which they have won twice and the Atlantic Cup, which they won in 2003. Moreover, in 1964, they became the first team from Iceland to compete in the European Cup. They have since gone on to compete in a number of different continental tournaments.
Well-known players to have played for KR include Ríkharður Daðason, Brynjar Gunnarsson and Kristján Finnbogason. Historically, the club have often had a Scottish presence within the side, with David Winnie and Jim Bett serving as notable examples. One of the all-time great Icelandic talents, Eiður Guðjohnsen, also had a brief spell with KR during the 1990s.
Since 1984, the team's home matches have been held at KR-völlur, which was built in 1951. The venue is currently able to hold a maximum of 2,781 spectators, although its record attendance figure was set at 5,400 spectators for a game against ÍBV in 1998.
