Härjedalen Municipality (Swedish: Härjedalens kommun) is a municipality in Jämtland County in northern Sweden. Its seat is located in Sveg.
The municipality roughly, but not exactly, corresponds with the traditional province Härjedalen.
The municipality was created in 1974 and is one of two in Sweden with the name of a province (Gotland Municipality is the other). It consists of nine original local government entities (as of 1863).
With a total area of 11,935 km², it is Sweden's fifth largest. However, it is largely wilderness, and the municipality is sparsely inhabited. For comparison, the municipality covers as much territory as Uppsala County and Stockholm County combined, but those two counties have over 2,000,000 inhabitants.
The population has been in decline in the last decades. The birth/death rate is negative, and so is net migration.
