The Acadian Peninsula (French: Péninsule acadienne) is situated in the northeastern corner of New Brunswick, Canada, encompassing portions of Gloucester and Northumberland Counties.
Most settlement in the peninsula occurred as a result of the Expulsion of the Acadians during the Gulf of St. Lawrence Campaign (1758), where British personnel forcibly removed them from their homes, mostly in southern New Brunswick and Nova Scotia.
Fishing is the dominant industry on the peninsula, with a large agricultural sector as well.
Peat bogs are found in the Shippagan and Lameque areas.
Major towns on the Acadian Peninsula include:
