Knattspyrnufélagið Valur (English: Falcon Football Club) is an Icelandic athletic club based in Reykjavík, Iceland. It celebrated its 100th birthday in May 2011. The club is situated close to the city centre, in the traditional east side of town, on the former farmland of Hlíðarendi. The club was originally formed as part of the local YMCA to play association football, but later incorporated handball and basketball. The club is the country's most prolific, looking at the national and cup titles amongst both men and women in the three biggest local ball sports: football, handball and basketball. Valur has a famous handball section, that reached the EHF Champions League final in 1980. It has won the Icelandic league 22 times, more than any other N1 deildin team.
The club was founded on 11 May 1911, as a subdivision of KFUM, the Icelandic YMCA. Later the same year its name changed to Valur, which is an Icelandic word for gyrfalcon. In 1930 the club won its first national title, and it has been amongst the best football teams in the country ever since. In 1939 Valur bought the farmland of Hlíðarendi which retains its name even today, where they currently practice and play, and where they now have a full-fledged[clarification needed] football field and an indoor arena. Originally Valur played only football, but around 1940 the club got involved in more sports, first team handball where they won the first national title and also reached the final of the EHF Champions League in 1980, and later skiing. In the post-war era (1948), a women's handball division was started at Valur and in the 1970s a women's football division. In 1970, Körfuknattleiksfélag Reykjavíkur (Reykjavík Basketball Club, KFR) joined Valur and became their basketball division.
The grounds at Hlíðarendi were completely restructured in the years between 2004 and 2007 and Valur currently play their home games at Vodafonevöllurinn ("The Vodafone Field"), and the handball games in the new Vodafonehöllin ("The Vodafone Hall"), the first section of the new grounds to be utilized. The new football pitch was used for the first time in the 2008 season. Reconstruction of Hlíðarendi will then be finalized with an indoor football pitch.
In June 2007 the club signed a 5 year sponsorship deal with Vodafone.
