Marguerite Porete, French mystic
Marguerite Porete (French: [maʁɡ(ə)ʁit pɔʁɛt]; 13th century – 1 June 1310) was a French-speaking mystic and the author of The Mirror of Simple Souls, a work of Christian mysticism dealing with the workings of agape (divine love). She was burnt at the stake for heresy in Paris in 1310 after a lengthy trial, refusing to remove her book from circulation or recant her views.

Today, Porete's work has been of interest to a diverse number of scholars. Those interested in medieval mysticism, and more specifically beguine mystical writing, cite The Mirror of Simple Souls in their studies. The book is also seen as a primary text regarding the medieval Heresy of the Free Spirit. Study of Eckhart has shown a similarity between his and Porete's ideas about union with God. Porete has also been of interest to those studying medieval women's writing.
