=== 1945–1969: Two Northern-Norwegian cup championships ===
Tromsø started the post-war years in a good fashion, winning the club's sixth district championship in 1946. In 1949, Tromsø won its second Northern Norwegian cup. This time, the final match was played at Harstad Stadium, and Tromsø were to play [[FK Bodø/Glimt]]. Tromsø won 3–1, just like in 1931.

Tromsø then won five consecutive district championships between 1950 and 1954, before the club was introduced into the Norwegian league system (Northern Norwegian clubs could still not be promoted to the top division, however). The club's third and last Northern Norwegian cup came in 1956. Tromsø met [[Harstad IL]] – the champions of the previous three years – in [[Harstad Municipality|Harstad]], making Harstad the favourites. However, Tromsø won the match 2–0.

Clubs from Northern Norway were allowed into the Norwegian [[Norwegian football cup|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.
