Úrvalsdeild karla; English: Men's Premier League, also known as Subway deildin for sponsorship reasons, is the highest men's professional basketball competition among clubs in Iceland, where play determines the national champion. It is organized by the Icelandic Basketball Federation (Icelandic: Körfuknattleikssamband Íslands - KKÍ). The season consists of a home-and-away schedule of 22 games, followed by an eight-team playoff round. Quarterfinals, semifinals and finals series are best-of-five. The bottom clubs are relegated, and replaced by the top team from the regular-season phase and the four-team playoff round winner of the second-level First Division (Icelandic: 1. deild karla).
