Agnieszka Machówna (c. 1648 – 12 July 1681) was a Polish con artist and bigamist. Born in the peasantry, she is famous for her fraud in posing as a member of the Zborowski family. She was convicted of forgery, theft, adultery, and perjury, and was sentenced to death.

Machówna was born around 1648 in the village of Kolbuszowa. Her father was a military drummer and her mother was a peasant woman. Machówna likely was baptised under the name Jadwiga.^[1] Her mother worked as a servant at the Lubomirski Palace, and Duchess Helena Tekla Lubomirska sent her to a local parish priest to teach Machówna to read and write. She married Bartosz Zatorski, the court Cossack of the Lubomirski family, at age 16. Zatorski was prone to beating her in fits of drunken rage, and Machówna was unhappy with her life in Kolbuszowa, wanting a more opulent life than what she had there. She ran away to Kraków, and later moved to Warsaw.^[2] Machówna claimed to be Aleksandra Zborowska, daughter of Marcin Zborowski. Machówna took advantage of the fact that the Zborowski family was nearly extinct, so her story was not questioned. She said that she hid from enemy troops as a child and stayed in many manors.^[1]

She then married Kollati, a wealthy officer of the Austrian army who was staying at the court of Eleonore of Austria, but he abandoned her so that he could become involved with other women in Vienna. After Kollati left her, Machówna married Stanisław Rupniowski, the 16-year old castellan of Biecz, who married her and took her to Paris. After Rupniowski died, Machówna returned to Poland and took over her deceased husband's estates.^[1][3] Rupniowski's sister, Anna Szembekowa, suspecting fraud, brought a lawsuit against her at the Crown Tribunal in Lublin, but Machówna failed to appear before the court. Machówna seduced Stanisław Domaszewski, the starosta of Łuków, and married him. Domaszewski was bribed by the Rupniowski family, so he tricked Machówna into coming to the Crown Tribunal using the lie that they were taking a walk. Machówna was arrested and put in prison.^[2]

Machówna was convicted of forgery, theft of property, adultery, and perjury and was sentenced to have her breasts torn off with pliers and then be beheaded,^[1] but the first part of the punishment was not carried out. Machówna was executed on 12 July 1681 by the Lublin executioner.^[2]

Polish poets Wespazjan Kochowski and Jan Gawiński both wrote poems commerating Machówna's death. In both of the poems, she is presented "bidding farewell to the world".^[3] Nierządnicy żywot atłasowy, a 1972 novel by Jan Ziółkowski, follows Machówna's life.^[4]
