Reykjavík Cathedral (Icelandic: Dómkirkjan í Reykjavík) is a cathedral church in Reykjavík, Iceland, the seat of the Bishop of Iceland and mother church of the Evangelical Lutheran Church of Iceland, as well as the parish church of the old city centre and environs. It is located at Austurvöllur, and next to it is Alþingishúsið (the parliament house). Since Iceland's parliament, the Alþingi, was resurrected in 1845, each session of parliament has begun with a mass at the cathedral, and from there the dean of the cathedral leads the members of parliament to the parliament house.
