Antonio or Anthony Ravalli (b. in Ferrara, Italy, 16 May 1812; d. at St. Mary's, Montana, USA, 2 October 1884) was an Italian Jesuit missionary, artist, and doctor active in the Pacific Northwest region of the United States. He is known primarily for his contributions to the architecture and art of Jesuit missions in the region. He also inoculated the tribes he served against smallpox, and his efforts shielded the Bitterroot Salish against epidemics that devastated other tribes. In 1893 Ravalli County, Montana was named after him.
