HISTORY

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.
