1983 Icelandic Cup
The 1983 Icelandic Cup was the 24th edition of the National Football Cup.
It took place between 23 May 1983 and 28 August 1983, with the final played at Laugardalsvöllur in Reykjavík. The cup was important, as winners qualified for the UEFA Cup Winners' Cup.
The 10 clubs from the 1. Deild entered in the last 16, with clubs from lower tiers entering in the three preliminary rounds. Teams played one-legged matches. In case of a draw, the match was replayed at the opposition's ground.
