Jämtland County (Swedish: Jämtlands län, Southern Sami: Jiemthen leene) is a county or län in Sweden. It consists of the provinces of Jämtland and Härjedalen, along with minor parts of Hälsingland and Ångermanland, plus two small strips of Lapland and Dalarna. It borders the counties of Dalarna, Gävleborg, Västernorrland, and Västerbotten, as well as the Norwegian county of Trøndelag. It measures 49,443 km (19,090 sq mi) and constitutes 12% of Sweden's total area, making it the country's third largest county. The capital is Östersund. The county governor and leader of the administrative board, as appointed by the Swedish government, has been Marita Ljung since 2021.

The county was established in 1810, at which time it consisted only of the provinces of Jämtland and Härjedalen, which is why the coat of arms is a shield parted per fess with their provincial arms. His Majesty King Carl XVI Gustaf is occasionally referred to as Duke of Jämtland after his title of king.

Jämtland County consists of primarily the provinces of Jämtland and Härjedalen, though minor parts of Hälsingland and Ångermanland are also included, along with small uninhabited areas in Lapland and Dalarna.

The main aim of the County Administrative Board is to fulfill the goals set in national politics by the Riksdag and the Government, to coordinate the interests and promote the development of the county, to establish regional goals and safeguard the due process of law in the handling of each case. The County Administrative Board is a Government Agency headed by a Governor. See List of Jämtland Governors.

Jämtland County is sparsely populated and more than one-third of the population lives in the countryside, making Jämtland County the second largest rural region in Sweden, after Gotland County. However, most of the population lives in the rather densely populated region surrounding lake Storsjön, commonly called Storsjöbygden, "the Storsjö district/countryside".

The county is dominated by the Swedish Social Democratic Party and the Centre Party, which is unique in Sweden, but corresponds to the situation in the bordering Norwegian county of Nord-Trøndelag. The county is rather contrastive in the political field. While the municipality association and a majority of the municipalities are governed by liberal-conservative (Swedish: borgerlig, lit. "bourgeois") majorities or by coalitions overstepping the bloc border, the county council is red-green and the Social Democrats receive three out of five mandates to the Riksdag.
