The Battle of Bysjön was fought between Swedish and, for the most part, Norwegian troops on 22 December 1644. The battle took place on the ice of the frozen Lake Bysjön in the parish of Eda (Eda socken, Värmland) in Värmland, Sweden. The battle was part of the Torstenson War (1643–1645), known locally as the Hannibal Feud (Hannibalsfejden) between Sweden and Denmark-Norway. The Dano-Norwegian victory meant the invading army could potentially continue into Värmland and Dalsland.
