Clubs from Northern Norway were allowed into the Norwegian cup in 1963, and Tromsø participated for the first time in 1964, advancing to the second round after beating FK Mjølner. The club was eliminated in the second round by Nidelv IL. The 1960s were also a period of stadium expansions for the club, with both Valhall Stadium and Alfheim Stadium getting grass fields. Because of the inclusion of Northern Norwegian clubs in the Norwegian Cup, the Northern Norwegian Cup was eventually dropped. Tromsø played its last Northern Norwegian Cup match in 1969.
