Savina Petrilli (29 August 1851 - 18 April 1923) was an Italian Catholic professed religious who founded the Sisters of the Poor of Saint Catherine of Siena upon receiving the encouragement of Pope Pius IX.

She is commemoration in the current edition of the Roman Martyrology on 18 April,[3] Where the entry (in Latin) reads 'Siena in Tuscany, Blessed Savina Petrilli, virgin, who founded the Congregation of the Sisters of St Catherine of Siena to bring aid to needy girls and to the poor.'

[4] Along with five others, Savina made her profession as a religious on 15 August 15, 1873, which is regarded as the date of foundation of her congregation in a little chapel in her family's house.

Rome subsequently granted a decree of ratification to what had been achieved by the diocesan process at Siena, recognizing that it had completed all the tasks assigned to it.

In 198r, the Positio - a large dossier on Savina's religious activity as well as a biographical account - was compiled and submitted to the Congregation for the Causes of Saints for its own examination.

The positive results led to Pope John Paul II proclaiming Savina Petrilli to be Venerable on November 16, 1985.

On April 24, 1988, in Saint Peter's Square, the Pope celebrated the solemn Mass during which he beatified Savina Petrilli.
