João Álvares Fagundes (born c. 1460, Kingdom of Portugal – died 1522, Kingdom of Portugal) was an explorer and ship owner from Viana do Castelo in Northern Portugal. He organized several expeditions to Newfoundland and Nova Scotia around 1520–1521.
Fagundes, together with his second captain Pero de Barcelos, and accompanied by colonists (mostly from the Azores and some from mainland Portugal), explored the islands of St Paul near Cape Breton, Sable Island, Penguin Island (now known as Funk Island), Burgeo, and Saint Pierre and Miquelon. He named the latter islands as the Eleven Thousand Virgins, in honor of Saint Ursula.
