List of islands of Maine

Maine is home to over 4,600 coastal islands, ranging from large landmasses like Mount Desert Island to small islets and ledges exposed above mean high tide.

The Maine Coastal Island Registry (CIR)

The Maine Coastal Island Registry (CIR) catalogs 3,166 of these coastal islands, along with some notable inland freshwater islands, such as Frye Island in Sebago Lake. According to the most recent CIR data, 1,846 islands are registered to private owners, while 204 islands, which contain four or more structures, are exempt from registration. Additionally, 1,322 islands are under the care and custody of the State of Maine. The table below uses CIR as its primary source; additional sources are cited.

Description of table columns

The table below provides information on Maine islands, organized by several key columns. Below is an explanation of each column.

Registry #: The unique identifier assigned to each island by the Maine Coastal Island Registry (CIR). Multiple islands may share the same name, but each has a distinct registry number. Islands with multiple landmasses may have several registry numbers under a single name.

Island name/other name(s): The primary name of the island, along with any additional names it may be known by.

Town/county: Identifies the town and county associated with the island. This serves as a reference point, as Maine's islands often have complex jurisdictional histories, including independent towns, parts of mainland municipalities, or self-governing plantations.

Code: Indicates the island's registry status:

R: Registered
U: Unregistered
E: Exempt
T: Transferred
L: Leased

Description: Brief information about the island's features, as well as notable owners of these islands. Descriptions and acreage may vary due to changes like construction or natural events.

Area: The size of the island in acres, where available.
