Campobello Island is the largest and only inhabited island in Campobello, a civil parish in southwestern New Brunswick, near the border with Maine. The island's permanent population in 2016 was 872. It is the site of the Roosevelt Campobello International Park and of Herring Cove Provincial Park.
It has been governed as an incorporated rural community since 2010 but still receives some local service district services from the province, being assessed for fire protection, policing, dog control, and general government, and is a member of the Southwest New Brunswick Service Commission. Despite the name, the rural community also includes all other islands in the parish.
