Treaty of Lödöse was a peace treaty between Sweden and Norway in 1249. It ended a 24-year period of mutual hostility that had erupted after Norway's infamous Värmland expedition in 1225. Attempts for peace had already started in 1241, but could not be concluded before years later. The tensions between the countries had not escalated to open war.

The treaty resulted in no border changes. The contents were as follows:

• Neither kingdom would support the enemies of the other

• Neither kingdom would give refuge to the enemies of the other

• Mutual friendship would be maintained by both parties.

In addition and before the actual negotiations got started, King Haakon IV of Norway and Birger Jarl, the true regent in Sweden, agreed on a marriage between Birger's daughter Rikissa and king's son Haakon.
