1971 Icelandic Cup
The 1971 Icelandic Cup was the 12th edition of the National Football Cup. Víkingur Reykjavík were winners.
It took place between 7 July 1969 and 9 December 1969, with the final played at Melavöllur in Reykjavík. The cup was important, as winners qualified for the UEFA Cup Winners' Cup.
Clubs playing in Europe did not enter until the quarter-finals. Other teams from the 1. Deild, entered at the fourth round. As with previous years, teams from the 2. Deild and 3. Deild played in one-legged matches. In case of a draw, the match was replayed.
Víkingur Reykjavík became the first 2. Deild team to win the competition, beating newly promoted Breiðablik Kopavogur in the final by the narrowest of margins. It was the first national trophy for the club who had a memorable season: this trophy, promotion to the 1. Deild, and qualification for Europe.
