The Saint Susanna is a marble sculpture by François Duquesnoy. The work is one of four sculptures of Roman virgin martyrs commissioned by the Bakers' Guild to decorate the church of Santa Maria di Loreto in Rome. It was completed in the course of four years from 1629 to 1633. Giovanni Pietro Bellori, comparing Duquesnoy's achievement with the Saint Susanna to that of Polyclitus with his Doryphoros and its Kanon, commented [Duquesnoy has] left to modern sculptors the example for statues of clothed figures, making him more than the equal of the best ancient sculptor. The statue is considered by modern scholars an exemplification of Duquesnoy's 'Greek ideal,' which included an approach to drapery unpopular at the time, established through the study of antique models selected by Duquesnoy.

François Duquesnoy or Frans Duquesnoy was a Flemish Baroque sculptor who was active in Rome for most of his career, where he was known as Il Fiammingo. His idealized representations represented a quieter and more restrained version of Italian baroque sculpture, and are often contrasted with the more dramatic and emotional character of Bernini's works, while his style shows a great affinity to Algardi's sculptures.
