Giordano Ansaloni was a 17th-century Italian Dominican missionary who served in Asia. Born in Santo Stefano Quisquina, Sicily, he studied in Salamanca before being sent to the Philippines in 1625. While working as a chaplain in Manila, he acquired proficiency in Chinese and Japanese languages. He later traveled to Japan during a period of intense religious persecution, where he disguised himself to continue his religious work. He is recognized as a saint in the Catholic Church for his martyrdom in Nagasaki.
