Leiknir is an Icelandic football club in the suburb of Breiðholt in Reykjavík. The male team is a member of Fyrsta Deild, the league below Landsbankadeildin, the top division in the Icelandic football ladder. The club runs a youth setup in its district for boys and girls aged 6-16, but does not participate in the Women's league competition. A basketball team also plays in the lower leagues of the Icelandic basketball ladder using the name of the club, although the club does not run youth programs for basketball.
Work is well underway on a new clubhouse, which will replace the cabin that had served as the clubs office and dressing facility since the the clubs foundation. The new facility will be around 1000 square meters in size, which is an epic increase over the now demolished 50 square meter cabin.
