The Strait of Juan de Fuca (called Juan de Fuca Strait in Canada) is a large body of water about 95 miles (153 km) long forming the principal outlet for the Georgia Strait and Puget Sound, connecting both to the Pacific Ocean. It provides part of the international boundary between the United States and Canada.
It was named in 1787 by Charles William Barkley, captain of the Imperial Eagle, for Juan de Fuca, the Greek navigator who sailed in a Spanish expedition in 1592 to seek the fabled Strait of Anián. Barkley was the first non-indigenous person to find the strait, unless Juan de Fuca's dubious story was true. The strait was explored in detail between 1789 and 1791 by Manuel Quimper, José María Narváez, Juan Carrasco, Gonzalo López de Haro, and Francisco de Eliza.
