Keflavík Youth Club (Ungmennafélag Keflavíkur, UMFK) was founded on 29 September 1929 by 28 young people in the town of Keflavík. The club became a member of The Icelandic Youth Federation which had been established in 1907 as part of Iceland's drive for independence. The Keflavík Youth Club was a typical youth club of the era; forming teams in swimming and athletics, teaching physical education, putting on theatre productions and supporting various local causes. An important part of the Youth Federation was appreciation for the country and its people and the movement was especially active in rural areas and small towns.[8]

On 12 July 1950 a second sports club was founded in Keflavík, the Keflavík Football Club (Knattspyrnufélag Keflavíkur, KFK). Despite its name, the club formed teams in football, handball and swimming.[9]

With two major sports clubs in the small town of Keflavík it was felt that resources were being spread too thin. On 18 March 1956 a new club was formed, Keflavík Sports Federation (Íþróttabandalag Keflavíkur, ÍBK). Similar sports federations were formed in towns around Iceland. The idea behind them was that various groups and clubs could come together to represent the town in various sports, often against other towns. Another aim was to enable sportsmen from smaller towns to compete against the bigger clubs from Reykjavík, especially in football and other team sports. The town federations also represented the town's clubs within national associations. In Keflavík the existing clubs were not disbanded but their operations were limited. Keflavík Youth Club continued to work within the national youth movement, mainly on social and cultural issues. Sporting activities within the youth club and Keflavík Football Club were virtually non-existent, although the youth club participated in the semi-annual national youth festival. The two clubs also played against each other in team sports like football and handball on special occasions in the town, like Independence Day.[10]

In 1994 the town of Keflavík merged with its neighbouring towns of Njarðvík and Hafnir to form a new municipality, Reykjanesbær. A new sports federation was formed for the new town, Reykjanesbær Sports Federation (Íþróttabandalag Reykjanesbæjar, ÍRB). With the Keflavík club no longer a sports federation it was decided to form a new club, Keflavík Sports and Youth Club (Keflavík, íþrótta- og ungmennafélag), which was to be commonly known as Keflavík. The youth in the title was to indicate that the club was a member of The Icelandic Youth Federation. The new club also became a member of The National Olympic and Sports Association of Iceland (Íþrótta- og Ólympíusamband Íslands, ÍSÍ) and Reykjanesbær Sports Federation.
