Château Menier, French villa on L'Île-d'Anticosti, Canada.

Château Menier was a mansion at the head of Gamache Bay on L'Île-d'Anticosti, built between 1900 and 1905 by contractors Albert and Joe Peters to plans by architect Stephen Sauvestre for island owner Henri Menier. Nothing of the building stands today: it was burned down on 3 October 1953.

Henri Menier, owner of Anticosti Island, commissioned the residence; contractors Albert and Joe Peters built it between 1900 and 1905 to plans by architect Stephen Sauvestre, at the head of Gamache Bay. After Henri's death his brother Gaston sold the island, and the new owner, Consolidated Pulp & Paper, had the building burned down on 3 October 1953.

The château's name comes from Henri Menier, the French chocolate manufacturer who owned Anticosti and commissioned the residence; his brother Gaston inherited the island and sold it, after which the house stood abandoned. Visitors today find no ruins to explore: the building was burned on 3 October 1953, so the site at the head of Gamache Bay holds only traces of the former residence.

The château stood at the head of Gamache Bay, in what is now L'Île-d'Anticosti municipality; nothing of the building survives, so there is no structure to enter or tour. Access to the island is by ferry or boat from the mainland, and the former site lies in a remote area with few facilities, so plan transport and supplies before setting out.

The château was deliberately burned down on 3 October 1953 by Consolidated Pulp & Paper, the company that had bought the island after Henri Menier's heir, his brother Gaston, sold it. The fire, not decay, ended the building.
