Port Discovery, Washington is the historical name of what is now called Discovery Bay, a bay in the U.S. state of Washington on the south side of the Strait of Juan de Fuca, on Washington's Olympic Peninsula. It was also called Port Discovery Bay for some time, a name that can be found on maps from the 1940s and earlier. Port Discovery is also the name of a historically significant community that was located on the bay for roughly a hundred years; it disappeared in the late 20th century, with the collapse of the local timber industry.
The bay was first visited by Europeans in 1790, during the expedition of Manuel Quimper in the Princesa Real, with Juan Carrasco as pilot. They gave it the name Puerto de Quadra, after Juan Francisco de la Bodega y Quadra, their commander at San Blas. In 1791 Francisco de Eliza used Port Discovery as his base of operations for further explorations.
The name Port Discovery was given by George Vancouver in his 1792 visit to the Strait of Juan de Fuca, and honors his ship the Discovery. Vancouver's landing place was apparently at what was later called Carr Point (also Contractors Point).
Port Discovery was a regular port of call for ships traversing the Pacific until the mid 20th century, and in particular for many U.S. ships involved in World War II, such as USS Washington, USS Lassen, and USS Las Vegas Victory. The wreck of the War Hawk (clipper ship), which burned and sank in 1883, is a popular dive site in the bay, near Mill Point.
