1990 Icelandic Cup

The 1990 Icelandic Cup was the 31st edition of the National Football Cup.

It took place between 22 May 1990 and 27 August 1990, with the final replay played at Laugardalsvöllur in Reykjavik. The cup was important, as winners qualified for the UEFA Cup Winners' Cup (if a club won both the league and the cup, the defeated finalists would take their place in the 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, a penalty shoot-out took place (there were no replays, unlike in previous years).

For the first time in the history of the competition, the final finished in a draw after extra time. In contrast to other rounds, a replay took place, but this time, a penalty shoot-out took place when that match also ended in a draw. Valur Reykjavik won their sixth Icelandic Cup, and so qualified for Europe.
