During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the western part of the island of Tjeldøya (population: 297) was transferred to Tjeldsund Municipality from Lødingen Municipality, uniting the whole island within the same municipality. On the same date, the unpopulated Ramnes area of Evenes Municipality was also transferred to Tjeldsund Municipality.

On 1 January 2020, the municipality merged with the neighboring Skånland Municipality and at the same time the new municipality became a part of the newly formed Troms og Finnmark county (prior to the merger, Skånland was located in the old Troms county and Tjeldsund was in Nordland county).
