Anna Maria Taigi (née Giannetti; 29 May 1769 – 9 June 1837) was an Italian Catholic professed member from the Secular Trinitarians.

[1][2] Taigi reportedly experienced a series of ecstasies during her life and heard the voices of God and Jesus Christ on several occasions.

She became a Secular Trinitarian after experiencing a sudden religious conversion in the winter of 1790 at Saint Peter's Basilica, when Taigi came into contact with a range of cardinals and luminaries, including Vincent Strambi and Benedict Joseph Flaget.

On May 30, 1769, she was baptized in her local parish church as "Anna Maria Gesualda Antonia Giannetti".

Domenico served as a butler for the noble House of Chigi in the church of San Marcello al Corso.

A large throng saw her bump into the Servite priest, Father Angelo Verandi, in the piazza.

[2] On another occasion, Taigi entered the church of San Andrea della Valle.

"[2] On December 26, 1802, Taigi became a professed member of the Secular Trinitarians in the church of San Carlo alle Quattro Fontane.

[1][4] She frequented hospitals and especially liked to visit and aid patients at San Giacomo of the Incurables.

Taigi experienced a series of ecstasies and frequent visions in which she foresaw the future.

She knew a range of religious individuals, including Cardinal Carlo Maria Pedicini.

"[2] Before Taigi died, she met with the first Bishop of Louisville Benedict Joseph Flaget.

[3] Napoleon's mother, Letizia Ramolino, learned of Taigi and sought her spiritual advice.

Some of Taigi's spiritual advisors were Raffaele Natali, the secretary of Pope Pius VII and Vincent Strambi.

Taigi became acquainted with Cardinal Luigi Ercolani, and Giovanni Maria Mastai Ferretti who would become Pope Pius IX.

Pope Pius VII often asked Strambi how Taigi was doing and would send his blessings to her.

Pope Leo XII and Giuseppe Bartolomeo Menocchio both held her in high esteem.

She successfully foresaw that Cardinal Bartolomeo Alberto Cappellari would be elected as Pope Gregory XVI.

[6] Before Pius VIII died, Taigi and Natali went to San Paolo fuori le Mura.

She was buried at Campo Verano where, on the orders of Pope Gregory XVI, her remains were enclosed in a leaden sepulcher with seals affixed to it.

Odescalchi asked Natali to compile all documents so that Luquet could publish her biography.

On March 4, 1906, the confirmation of Taigi's heroic virtue allowed for Pope Pius X to name her as venerable.
