Decatur Island, Washington has a rich history shaped by the Coast Salish peoples, including the Lummi, Samish, and other Northern Straits tribes, who traditionally traveled through and utilized the island for fishing, shellfish harvesting, and seasonal camps. The island was later named by Spanish explorer Francisco de Eliza in 1791 in honor of Stephen Decatur, a U.S. naval officer, during early European exploration of the Salish Sea.
In the late 19th and early 20th centuries, Decatur Island was settled by homesteaders and fishermen, with small-scale farming, logging, and maritime trades forming the backbone of the island’s early economy. Over time, Decatur evolved into a quiet residential and retreat-oriented island, maintaining its rural character and deep respect for its natural environment. Today, the island reflects a balance of preserved landscapes, private ownership, and community stewardship rooted in both Indigenous heritage and pioneer history.
Located in San Juan County in northwest Washington State, Decatur Island sits within the Salish Sea, southeast of Lopez Island and just north of Cypress Island. Covering approximately 7.9 square miles, Decatur is home to a small population of roughly 200 residents, many of whom live part-time on the island.
Known for its tranquil setting, Decatur Island features forested hillsides, rocky shorelines, sweeping marine views, and abundant wildlife. With no commercial center and limited public infrastructure, the island offers a true off-the-grid island experience. Its proximity to Anacortes and neighboring San Juan Islands makes it accessible while still feeling remote, peaceful, and deeply connected to nature.
Decatur Island does not host large public festivals, but its close-knit community organizes informal gatherings, seasonal celebrations, and private events that foster strong neighborhood connections. Community potlucks, holiday gatherings, and stewardship projects are common among residents and reflect the island’s emphasis on collaboration and self-reliance.
Decatur Island’s annual sheep shearing event, held the first Saturday in May, is a beloved community tradition rooted in a 1986 effort to rescue and manage a wild, overgrown flock. What began as a critical health intervention—corralling and shearing over 150 sheep—has evolved into a yearly gathering where residents come together to care for the flock. Spectators fill the barn to watch the shearing while supporting sustainable flock management. Over time, the introduction of hardy Scottish Blackface sheep and ongoing stewardship has turned the event into both a celebration of local heritage and a vital part of maintaining the island’s unique ecosystem.
