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 and Sweden. It is named after the village of Knäred in Halland, where it was signed. As a result, Sweden had to pay the Älvsborg Ransom of one million Rixdollars for the return of the fortress of Älvsborg. The ransom was paid by 1619.
