The Abbe Museum is a museum with two locations in Bar Harbor, Maine, on Mount Desert Island. The museum is dedicated to exploring the history and culture of Maine's Native people, the Wabanaki. It has one location at 26 Mount Desert Street in the center of Bar Harbor, and a second location at Sieur de Monts in Acadia National Park. The Sieur de Monts building is an architecturally distinctive structure, listed on the National Register of Historic Places as one of the state's first purpose-built museum buildings, and as a rare example in the state of Mediterranean architecture.
