Blessed Savina Petrilli (†1923) was an Italian Roman Catholic professed religious who founded the Sisters of the Poor of Saint Catherine of Siena upon receiving the encouragement of Pope Pius IX. Petrilli devoted her order to the alleviation of the poor while catering to those people who came to the congregation seeking help. She opened her first international house in Brazil after her order was established and managed the house in Siena where she lived until her death from cancer in 1923. Her beatification was celebrated on 24 April 1988. Her feast in the liturgical calendar is assigned to 18 April.
