Havre-Saint-Pierre (French pronunciation: [avʁ sɛ̃ pjɛʁ]) is a municipality located on the north shore of the Gulf of St. Lawrence, in Côte-Nord region, Minganie RCM, Quebec, Canada.

In 1857, a group of Acadian families arrived, in 1872, the Parish of Saint-Pierre-de-la-Pointe-aux-Esquimaux was officially established, the same year its post office opened under the name Esquimaux Point.

Whether they were formed by erosion or sedimentation processes, or whether they were subjected to or resulted from extreme climatic events, or from the action of the sea and its estuary, morpho-sedimentological units bear witness to an extraordinary structural organization of the natural space.

The high latitude and low altitude, combined with the proximity of the cold currents of Labrador, explain the subarctic vegetation specific to the Minganie.

The entirely calcareous nature of the horizontal stratified rocks, which make up the Anticosti - Minganie, exerts a profound influence on the structure of the flora and on the choice of species.

[11][12] During the summers of 1964 and 1965, during geological research, Jean Depatie with a team of geologists and students, assisted by 3 canoemen and lumberjacks, plus a cook, explored 440 square miles of a territory stretching from Sept-Îles to Blanc Sablon, in the Lac à l'Ours region.

In the field, scientists noted an abundance of Canadian beavers, a few otters and American mink, many hares, partridges and a multitude of ducks.

[8] The waters of the St. Lawrence Estuary are internationally recognized as a vital feeding ground for rare or common species of marine mammals.

Many species of birds can be observed in the area of Havre-Saint-Pierre and in Mingan Archipelago National Park Reserve In spite of its maritime position just above the 50th parallel, Havre-Saint-Pierre has a relatively harsh subarctic climate, with cold winters and cool summers, although the fourth-warmest month of September is relatively close to the 10 °C (50 °F) isotherm to be cold humid continental.

[32] The Rio Tinto Iron and Titanium Company (RTFF) owns the easternmost of the ore ports on the North Shore in Havre-Saint-Pierre.

Its installation, between 1948 and 1950, included a mining shaft at Tio and Allard lakes, the construction of a 43 km railway line between this sector and Havre-Saint-Pierre, and the installation of a marine terminal[33] As is often the case on the middle and lower North Shore islands, in the Mingan Archipelago, the combination of irregular seabeds and strong tidal currents sometimes makes navigation perilous.

On the Mingan Banks, in the Jacques Cartier Strait, Anticosti Island and the North Shore form a large funnel where the easterly wind creates, among other things, an impressive swell.

[40] Ports of the Gulf of St. Lawrence, on the Côte-Nord Shore: Blanc-Sablon, Harrington Harbor, Natashquan, Havre-Saint-Pierre, Mingan, Port-Menier (Anticosti Island), Cap-aux-Meules (Îles-de-la-Madeleine).
