- Fram Reykjavik won their second Icelandic Cup and qualified for the 1974–75 European Cup Winners' Cup.
The 1973 Icelandic Cup was the 14th edition of the National Football Cup.
It took place between 13 June 1973 and 13 September 1973, with the final 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).
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.
Fram Reykjavik won their second Icelandic Cup, beating ÍBK Keflavík in the final. The club therefore qualified for Europe.
