The 1965 Icelandic Cup was the sixth edition of the National Football Cup.
It took place between 31 July 1965 and 31 October 1965, with the final played at Melavöllur in Reykjavík. 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). Teams from the Úrvalsdeild karla (1st division) did not enter until the quarter-finals. In prior rounds, teams from the 2. Deild (2nd division), as well as reserve teams, played in one-legged matches. In case of a draw, the match was replayed.
For the first time in 5 years (since the creation of the tournament), KR Reykjavík were eliminated when they entered, in the quarter-finals. Valur Reykjavík won the Cup, beating IA Akranes 5 - 3 in the final.
