Jacques Cartier (Breton: Jakez Karter; 31 December 1491 – 1 September 1557) was a French-Breton maritime explorer for France. Jacques Cartier was the first European to describe and map the Gulf of Saint Lawrence and the shores of the Saint Lawrence River, which he named "The Country of Canadas" after the Iroquoian names for the two big settlements he saw at Stadacona (Quebec City) and at Hochelaga (Montreal Island).
