Zygmunt Gorazdowski (1 November 1845 – 1 January 1920) was a Polish Roman Catholic priest and the founder of the Sisters of Saint Joseph. Gorazdowski suffered from tuberculosis during his childhood which impeded his studies for the priesthood in what required him to take time off in order to recover before he could be ordained. Once he was ordained he served in various parishes while setting up homes for orphans and single mothers as well as hospices and other establishments for a range of people; he was a prolific writer of catechism and other religious notes for the benefit of his flock.
