Fort Menagoueche was a French fort at the mouth of the St. John River, New Brunswick, Canada. French Officer Charles Deschamps de Boishébert et de Raffetot and Ignace-Philippe Aubert de Gaspé built the fort during Father Le Loutre's War and eventually burned it themselves as the French retreated after losing the Battle of Beausejour. It was reconstructed as Fort Frederick by the British.

Charles Deschamps de Boishébert was a member of the Compagnies Franches de la Marine and was a significant leader of the Acadian militia's resistance to the Expulsion of the Acadians. He settled and tried to protect Acadians refugees along the rivers of New Brunswick. At Beaubears National Park on Beaubears Island, New Brunswick he settled refugee Acadians during the Expulsion of the Acadians.
