Trijn van Leemput (c. 1530–1607) was a Dutch heroine of the Eighty Years' War against Spain. According to local legend in Utrecht, she led a large group of women on May 2, 1577 to the castle of Vredenburg and gave the signal to begin demolishing the castle. She is also said to have fought two Spanish soldiers, who were lodged at her house, at an earlier occasion. After catching them stealing, she threw one down the stairs and threatened the other with a knife.
