St. Ignace Island, which is uninhabited, is situated near the north shore of Lake Superior at the entrance to that lake's Nipigon Bay, in Northern Ontario. The English name is a translation of the original French name given it by Jesuit missionaries in honor of their founder St. Ignatius of Loyola. The island is clearly depicted on the 1669 map "Lac Tracy ou Superieur avec les dependances de la Mission du Saint Esprit" attributed to Claude-Jean Allouez and Jacques Marquette.{{Cite web |url=http://rla.unc.edu/Mapfiles/HMC2/F30-2-6.jpg |title=Lac Tracy ou Superieur avec les dependances de la Mission du Saint Esprit (map) |archive-date=April 25, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120425092859/http://rla.unc.edu/Mapfiles/HMC2/F30-2-6.jpg}}
