Ragged Island (Harpswell, Maine) is a privately owned island in Harpswell, Maine, United States, in Cumberland County, which is geographically within Casco Bay in the Gulf of Maine. It is located at .
Ragged Island is notable as having been the summer home of poet Edna St. Vincent Millay and husband Eugen Jan Boissevain from 1933 until her death in 1950. It is now a private residence.[1]
Whatever the history of the island's name, at least one 1790 maritime chart identifies it simply as Cold Arse.[2]
Ragged Island provides habitat for a large and diverse population of nesting seabirds, including the eider duck, black guillemot, greater black-backed gull, herring gull and osprey. Maine Coast Heritage Trust led an effort to protect the island, and in 2008 the U.S. Fish and Wildlife Service’s National Coastal Wetlands Conservation Grant program awarded a $323,000 Coastal Wetland grant to purchase a conservation easement on the property. The easement, held by Maine Coast Heritage Trust, permanently protects the 76.6acres natural area used by seabirds for nesting on Ragged Island.[3]
