Kårböle Redoubt, Historical redoubt in Färila socken, Sweden.

Kårböle Redoubt is a 17th-century fortification on the Ljusnan river, just southeast of Kårböle in Hälsingland. Its ramparts were built of two parallel timber walls with earth packed between them, and a moat originally about one metre wide and two metres deep ran outside. Major Mathias Francken had the moat deepened to nearly six metres and widened to almost nine metres in 1644.

Kårböle Redoubt was probably built during the Baltzarfejden war of 1611–1613, though it may date to the Nordic Seven Years' War around 1564. In 1644 Major Mathias Francken deepened the ditch to nearly six metres and widened it to nine, and added three redoubts on Skansberget. The garrison was about 500 men in 1657. It was decommissioned in 1679.

The name skans comes from the German Schanze, a term for field fortifications. The site lies at Kårböle, a crossroads on the Ljusnan that Swedish forces used as a gathering point in 1644. Since August 2019 a memorial stone at the redoubt commemorates the rescue work during the 2018 forest fires in Hälsingland.

The site is in a natural state and best reached on foot, as major access roads are some distance away. Limited facilities exist on site, so arriving prepared and checking conditions beforehand is advisable.

The site is registered in the Fornminnesregistret, Sweden's official record of archaeological and historical monuments. This designation means it receives formal protection status to ensure its preservation for future generations.
