Ippolito Galantini (14 October 1565 – 20 March 1619) was an Italian Roman Catholic and the founder of the Congregation of Christian Doctrine.
Galantini became a noted educator in Florence and Pope Leo XI - an associate of his - dubbed Galantini as the "Apostle of Florence" due to his activism in educational affairs.
He was subject to malicious attacks - even one failed assassination attempt - and was once accused of harboring heretical views though was exonerated from all charges.The beatification cause culminated with the confirmation of heroic virtue from Pope Benedict XIV in 1756.
Pope Leo XII later beatified Galantini in Saint Peter's Basilica on 19 June 1825.
