The Asticou Inn is an inn in Northeast Harbor, Maine. It was built in 1883. In 1899, it was destroyed by fire and rebuilt over two years. The rear of the building overlooks the Northeast Harbor inlet, which opens out to the Atlantic Ocean. The inn has been owned by the Asti-Kim Corporation since 1965 and, between 2015 and 2019, was managed by the Acadia Corporation. There are 48 guest rooms: 31 in the main inn, plus 17 in six adjacent buildings: Cranberry Lodge, Blue Spruce, Bird Bank, and three "Topsiders".
