Mette Iversdotter Dyre (Swedish: Mätta or Märta Ivarsdotter; c. 1465 – c. before 1533) was a Danish noble, nominal sheriff and chancellor.
In 1496, she married secondly to the Norwegian-Swedish noble Knut Alvsson Tre Rosor (d. 1502), who was a Norwegian riksråd and the fiefholder of Akershus Fortress in Oslo.
[2] While nominally in union with Denmark, Sweden was de facto an independent Kingdom with Svante as King in all but title, and Mette in the position as queen consort as the senior lady of the Swedish court: she fulfilled the same role as normally a queen consort, acting as a mediator for supplicants to her husband, and was referred to as "Princess" by officials.
A correspondence of about 40 preserved letters between Mette and Svante illustrates their close cooperation in politics, as well as their personal devotion to each other.
She was told that he was unavailable, and not informed that he was dead until her stepson, Sten Sture the Younger, had arrived to the castle and secured the regency for himself.
In 1515, Mette left Sweden for Denmark, where she appealed for the support of king Christian II of Denmark against Sten Sture the Younger in the dispute between her and her stepson about the inheritance of her late spouse, as Christian II was nominally the king of Sweden as well.
Christian II was unable to assist her in her dispute, but he appointed her sheriff, or (Lensmann) of the Bishopal Fief of Hørby near Holbæk, and Chancellor of St. Agnes' Priory, Roskilde.
As lensmann, she would have held general governing power over her fief, been in final command of its military and collected its taxes.
