The Jacques Cartier Strait (French: Détroit de Jacques-Cartier, pronounced [detʁwa də ʒak kaʁtje]) is an arm of the sea located in the Gulf of St. Lawrence, between the shore of Côte-Nord region and the North of Anticosti Island, in Quebec, Canada.

The other arm of the sea is the Honguedo Strait located on the south side of Anticosti Island and the Gaspé Peninsula.
The Jacques Cartier Strait is approximately 40 kilometres (25 mi) wide.
Jacques Cartier Strait was officially named for the French explorer Jacques Cartier in 1934 by the Geographic Board of Quebec to commemorate the 400th anniversary of his arrival in North America. Prior to this, it was also known as Détroit Saint-Pierre (by Cartier himself on August 1, 1534, the day of St. Peter), Labrador Channel (until 1815), and Mingan Passage.
The principal study areas include the Quebec North Shore in the Mingan Island / Anticosti region, the Gaspe Peninsula and St. Lawrence Estuary.

Jacques Cartier was a sufficiently experienced navigator to be asked by Francis I to undertake the official exploration of North America. There is no doubt that he was already familiar with the sea route that he took in 1534
