Pronounced “shuh big”, the island's name means “isle of many springs.” At almost five miles long and 1½ miles wide, it is the largest island in Casco Bay.

After seceding from the town of Cumberland, Chebeague Island became Maine’s newest independent town on July 1, 2007. The com­munity chose to secede to protect the future of its island elementary school, without which it would be extremely difficult to sustain a year-round population. In addition to fishing and local enterprises, a large number of islanders commute to mainland jobs.
