Härjedalen (Swedish pronunciation: [ˈhærjəˈdɑːlən]; Norwegian: Herjedalen, pronounced [ˈhærjəˈdɑːlən]) is a historical province or landskap in the centre of Sweden. It borders the country of Norway as well as the provinces of Dalarna, Hälsingland, Medelpad, and Jämtland. The province originally belonged to Norway, but was ceded to Sweden in the Treaty of Brömsebro, 1645.

The traditional provinces of Sweden serve no current administrative or political purposes, but are historical and cultural entities. In the case of Härjedalen there is a municipality, kommun, Härjedalen Municipality, which is located in the southern part of Jämtland County. The municipality does not exactly correspond to the province, but is larger.

The arms is represented with a dukal coronet. Blazon: "Argent a Sledgehammer Sable with Core Gules between Tongs of the second and two Hammers adorsed in pale of the second handled Gules.". It was granted in 1660. Since 1974 Härjedalen Municipality uses the same coat of arms, but without the coronet.

Four-fifths of the province is situated above 500 metres of altitude, constituting a part of the Scandinavian mountain range. Sweden's highest village Högvålen, at 835 metres, is also within the province.
