The Treaty of Knäred (Danish: Freden i Knærød, Swedish: Freden i Knäred) was signed on 21 January 1613 and ended the Kalmar War (1611-1613) between Denmark-Norway and Sweden. The peace negotiations came about under an English initiative. The peace was guaranteed by King James I of England and VI of Scotland.
The treaty was named after the village of Knäred in Halland, where it was signed at a border bridge in what was then the Danish Halland. The peace meant that both kingdoms restored the conquests made during the war. Under the terms of the treaty, Sweden would give back Jemtland and Herjedalen. Denmark would give back Borgholm, Kalmar and Öland.
A memorial stone over the site was erected between Knäred and Markaryd in 1925 by the Halland Art Museum (Hallands konstmuseum).
