Coos Bay is the largest city on the Oregon coast and has been the commercial hub of the region's southern reaches since the 1850s. Founded as Marshfield — named after the Massachusetts hometown of settler J. C. Tolman — the city incorporated in 1874 and only adopted the name Coos Bay in 1944. The name itself comes from a local Native American tribe and carries two meanings: lake and place of pines.
Before European settlement, the Confederated Tribes of Coos, Lower Umpqua and Siuslaw Indians and the Coquille Indians had lived in the region for thousands of years, relying on the Pacific, the bay's waterways, and the surrounding forests and meadows. Sir Francis Drake is believed to have sheltered near Cape Arago in 1579. By the mid-1800s, the same waterways and forests that sustained Native communities were drawing European settlers, and the economy shifted through coal mining, shipbuilding, and timber — industries that defined the Bay Area for over a century.
Today Coos Bay anchors a trio of communities known locally as the Bay Area, along with North Bend and Charleston. The surrounding coast offers dramatic scenery: the Cape Arago State Park headland with its seal and sea lion colonies, the botanical gardens at Shore Acres State Park, the sheltered cove at Sunset Bay State Park, and towering sand dunes at the Oregon Dunes National Recreation Area stretching north from town. In the city itself, the Coos Art Museum houses a notable memorial to local running legend Steve Prefontaine, while the Coos History Museum on the bayfront covers the region's Native American, maritime, and industrial heritage.
