Decatur Island is one of the group of Puget Sound islands known as the San Juans. It's located just east of Lopez Island, across Lopez Sound. Named for Stephen Decatur, it's approximately 3.5 square miles in area.
There's no Washington State Ferry service to Decatur. Access is by private boat, water-taxi or plane. There are no public facilities other than one public boat ramp.
In addition to the three private communities on Decatur (Decatur Northwest, Decatur Shores, and Decatur Head), there are about 180 full-time residents, served by one general store and a school for first through eighth grades. The 2000 census, however, reported a resident population of only 71.
