In 1844, the Troms area were separated from Vardøhus amt to form the new Tromsø amt (county). For the first 22 years, the Tromsø and Vardøhus counties shared an amtmann. It wasn't until 1866 that Tromsø got its own county governor. In 1919, the name was changed to Troms fylke. On 1 July 2006, the Northern Sami language name for the county was granted co-official (parallel) status along with Troms, so the names became or . From 1 January 2019 the County Governor offices of Troms and Finnmark were merged in anticipation of the merger of the two counties.
