Agnes of Denmark (1249 – after 1290) was the youngest daughter ofEric IV of Denmark and his wifeJutta of Saxony. She was the official founder of theSt. Agnes' Priory, Roskilde, becomingprioress there.^[1]

Agnes lost her father at the age of one, and after her mother left for remarriage inGermany, she and her sisters Ingeborg, Sophia and Jutta remained to be raised at the court of her paternal uncle, the king ofDenmark. The four sisters had the right to large estates after their father, but were not able to enforce them against their uncle, who deposed their father.

Her sisters Ingeborg and Sophia married the kings of Norway and Sweden respectively, and left Denmark with their inheritance. This was not to happen with Agnes and Jutta however. In 1264, a convent for women of the Dominican order,St. Agnes' Priory, Roskilde, was founded and named after her. The application was sent to thePope in the name of Agnes, and who expressed her wish to devote herself and her inheritance to the convent. The regent of Denmark,Margaret Sambiria, was forced to swear that Agnes had taken this initiative by her own freed will, before the approval was given. In reality, the Danish regent did not wish to have more of the large inheritance of the daughters of Eric IV leave Denmark, which would be the case if Agnes and her sister Jutta married foreign princes and left Denmark, as their sisters Ingeborg and Sophia had done.

After the foundation of St. Agnes' Priory, Agnes was placed there by the Regent Margaret as Prioress. In 1266, the regent placed her sister Jutta in the convent as well, replacing her as prioress.

Both sisters greatly disliked the life asnuns, and they both left the convent in 1270. Agnes seems to have managed to gain control over at least part of her father's estates. She lived the rest of her life managing her estates atSjälland, and there are several documents mentioning her acts as a landowner. She was last mentioned alive in 1290. The year of her death is unknown. Agnes supposedly married her cousinEric Longbone, Lord of Langeland.

The Danish Royal House and the Saint Agnes Abbey battled over her inheritance until theDanish Reformation.
