Algonquian–Basque pidgin
Algonquian–Basque pidgin, also known as Souriquois, is a Basque-based pidgin that linguist Peter Bakker proposed was spoken by ethnic Basque whalers and various Algonquian peoples around the Gulf of St. Lawrence; it was in use from at least 1580 until 1635, and was last attested in 1711.
