The House of Munsö is the Scandinavian semi-legendary dynasty which is descended from Björn Ironside, one of the sons of Ragnar Lodbrok. According to Saxo Grammaticus, it was a branch of the House of Yngling. It is named after the island on which Björn Ironside is reputedly buried. If the sources are correct, the dynasty was to rule Sweden from the late 8th century until 1060.

It is also called the House of Ivar and Ragnar Lodbrok, the Old Dynasty or the House of Uppsala.
