Ide Pedersdatter Falk (1358 – 15 August 1399), was a powerful Danish noble landholder and the founder of a convent.
Ide was the daughter of the noble Peder Eskildsøn and Ida Olufsdatter and a member of the Falk family, who previously belonged to one of the most powerful clans in Denmark.
She had no children who survived to adulthood, which made her a powerful landholder in Scania and gave her a dominant position within the Danish noble elite.
She is known for her will, in which she left provisions which are regarded to show solidarity with her own gender, as she donated enough money to every female to live an independent life.
She left the majority of her fortune to the foundation of a convent for females she wished to have built in Gladsax in Scania.
