Marianne Cope, OSF (also known as Marianne of Molokaʻi; January 23, 1838 – August 9, 1918) was a German-born American Religious Sister who was a member of the Sisters of St. Francis of Syracuse, New York, and founding director of its St. Joseph's Hospital in the city, among the first of 50 general hospitals in the country. In 1883 she led a group of six other Sisters to the Kingdom of Hawaii to care for persons suffering leprosy on the island of Molokaʻi and aid in developing the medical infrastructure in Hawaiʻi. Despite direct contact with the patients over many years, Cope did not contract the disease.
In 2005, Marianne was beatified by decision of Pope Benedict XVI. She was canonized (declared a saint) by the same pope on October 21, 2012, along with Kateri Tekakwitha, a 17th-century Native American. Cope was the 11th Catholic active in what is now the United States to be canonized by the Catholic Church.
