Marguerite de Navarre (1492-1549) was a French noblewoman, writer, and sister of King Francis I of France. She is best known for her literary work, particularly the collection of stories titled Heptameron, which reflects her interest in humanism and the complexities of love and morality.

As a patron of the arts, Marguerite supported various writers and thinkers, promoting the exchange of ideas during a period of religious and political upheaval in France.
