Säter Municipality, Municipality in Dalarna County, Sweden

Säter Municipality is an administrative area in Dalarna County, in central Sweden, covering forested land, lakes, and the Säter Valley. The Ljustern river runs through the valley and shapes the landscape across the whole area.

The area's four parishes—Gustafs, Silvberg, Stora Skedvi and Säter—became rural municipalities in 1862, while Säter town formed its own town municipality in 1863. In 1952 Silvberg was merged into Gustafs and Säter rural municipality into Säter town. The present municipality was created in 1971 from Säter town, Gustafs and Stora Skedvi.

In Skedvi kyrkby stands the Kaplansgården, a building protected as a listed monument and used as the parish's hembygdsgård. The municipality's coat of arms, already depicted in 1642 and confirmed by the King in the 1940s, shows a smith in a red cap raising a blue tool over a red iron billet.

The municipality is crossed by the Avesta Krylbo–Borlänge railway and by national road 70, which passes through the central town of Säter; national road 80 runs east–west through the north. The Säter Valley, about 5 km long with the Ljuster stream at its bottom, is popular for walking.

Silver was extracted in this area as early as 1480, and one of the local mines stayed in operation for over 600 years. That is an unusually long run for a single site and points to how central mining was to life here for so many generations.
