Monomoscoy Island, MA

Monomoscoy Island is a small census-designated place in Mashpee, set between the tidal Little River and Hamblin Pond on the northwest and the Great River on the southeast. The 2020 census counted 139 residents. Monomoscoy Road crosses the marsh to the mainland, which makes the name island a little loose: part of the CDP lies on the Cape Cod side of the road, and the road itself is the everyday link between homes and town services. This is one of those places where the map is mostly water, marsh, and a single access line.

Mashpee's working waterfront shows up in the local map names. Little River, Hamblin Pond, Lower Great River, and Jehu Pond all have designated mooring areas, while the town's natural-resources department manages waterways, shellfish, and public access. Monomoscoy Road West, Great River Road, and Hamblin Road make the community feel less like a remote island than a coastal neighborhood with a very specific geography. The local story is not a downtown or a main street; it is tidal circulation, marsh crossings, and the way a narrow road holds the place together.
