Maria Vittoria De Fornari Strata (1562 – 15 December 1617) was an Italian Roman Catholic nun and the foundress of the Order of the Annunciation – or Blue Nuns. Fornari was married for just under a decade and decided not to find another spouse after having a vision of the Madonna who instructed her to lead a chaste life of motherhood. The widow decided to found an order not long after this based on the Carmelite charism. Her beatification was held on 21 September 1828.
