Southwest (Althing constituency)

Southwest (Icelandic: Suðvestur) is one of the six multi-member constituencies of the Althing, the national legislature of Iceland. The constituency was established in 2003 following the re-organisation of constituencies across Iceland when the Reykjanes constituency was split between the new South and Southwest constituencies. Southwest is conterminous with the Capital region but excludes Reykjavík Municipality which has its own constituencies, Reykjavík North and Reykjavík South. The constituency currently elects 12 of the 63 members of the Althing using the open party-list proportional representation electoral system. At the 2024 parliamentary election it had 79,087 registered electors.
