The Penobscot people called it Pitaubegwimenahanuk, meaning "the island that lies between two channels." Situated in upper Penobscot Bay, the narrow, 14-mile island is the marker between East and West Penobscot Bay. It was part of the Waldo Patent. First called Long Island Plantation, it was settled in 1769. It was incorporated as Islesborough on January 28, 1789, although over time the spelling was contracted to Islesboro.
With many harbors and coves, the island was home to the largest commercial shipping fleet in the bay during the 19th century. Following the Civil War, however, Islesboro developed as a Gilded Age resort community, and many large summer homes were built by the wealthy. Their large yachts cruised and raced throughout the Gulf of Maine. The town remains an upper-class enclave and summer colony.
According to the United States Census Bureau, the town has a total area of 68.88 square miles (178.40 km2), of which 14.29 square miles (37.01 km2) is land and 54.59 square miles (141.39 km2) is water.
There is one large pond, called Meadow Pond, in the Northern portion of the Island, the work of beavers that have dammed a narrow place. Ice was once harvested from this pond for export to places as far away as India. Hewes Point was named for Paola Hewes, an early pioneer settler.
This climatic region is typified by large seasonal temperature differences, with warm to hot (and often humid) summers and cold (sometimes severely cold) winters. According to the Köppen Climate Classification system, Islesboro has a humid continental climate, abbreviated "Dfb" on climate maps.

Islesboro Central School is one of four island schools in Maine that cover all grades (K-12), the others being North Haven, Vinalhaven, and Mount Desert Island. It is also unique that it allows mainland students to pay tuition to attend from grades 5-12. The "magnet" students, and some teachers, who live on the mainland take the ferry across every morning where they are met with a school bus to take them to school. Students come from a range of midcoast towns to attend ICS. The number of the students in the school fluctuates, but is around 100 students in kindergarten through 12th grade.
The school is a member of the Busline League for middle school sports, and is in Class D, South, in the Maine Principals' Association. The competitive sports offered through the school include cross country running, sailing, soccer, basketball, and Ultimate Frisbee.
