Margareta (c. 1369 – c. 1414) was a Swedish Sami missionary. Between about 1388 and 1414, she travelled around Sweden asking churches for support in spreading Christianity to the Sami people. In 1389, her campaign prompted a letter from the Swedish crown and the Archbishop of Lund in support of the mission. Her role is noted as unusual because of her position as a woman and a Sami.
