Giuditta Vannini – also known as Giuseppina – was an Italian religious sister of the order which became part of the Camillians. Together with Luigi Tezza she established the religious congregation known as the Daughters of Saint Camillus. She and her two siblings were orphaned as children and were placed in different homes; she was raised and educated in Rome under nuns where her vocation to the religious life was strengthened. Vannini later tried joining a religious order but was forced to leave during her novitiate period after suffering from ill health. She and Tezza met in 1891 and founded a religious congregation of which Vannini served as Superior General until her death while Tezza was exiled to Peru around 1900.
