L'Île-d'Anticosti is a municipality located on the Anticosti island, between the straits of Jacques Cartier and Honguedo, in the Gulf of St. Lawrence, in Minganie Regional County Municipality, Côte-Nord region, Quebec, Canada.

Toponymy

Within the municipality, the main populated area is Port-Menier. Officially the municipality was formed first in 1902 when Anticosti Island was separated from the County of Saguenay. But since the entire island was privately owned, there was no elected council to preside over the islanders, who were either servants of the landlord or employees of logging companies. Even after the island was owned again by the provincial government in 1974, it took another decade to put a working municipal organization in place. On January 31, 1984, the first council was finally sworn in.

UNESCO's World Heritage

On September 19, 2023, Anticosti was inscribed on UNESCO's World Heritage List. It is recognized for its exceptional fossil assemblage representing the first global mass extinction of animal life on Earth. Located within protected areas free from any industrial activity, the site is endowed with exceptionally well-preserved, abundant and diverse fossil fauna, this Anticosti fauna represents the first mass extinction of animal life on a global scale, 447 – 437 million years ago, at the end of the Ordovician period. The Vauréal River has its source in Lake Vauréal, it flows 25 km south-northeast, in the eastern part of the island.
