Barnes Island is a small island in the San Juan Islands of the U.S. state of Washington. It is located near Clark Island off the northeast coast of Orcas Island.
The name was given by Charles Wilkes during the Wilkes Expedition of 1838-1842, to honor a sailor who was killed during the Battle of Lake Erie of the War of 1812. The island, along with nearby Clark Island, had been named in 1792 Islas de Aquays, by the Spanish explorer Francisco de Eliza, in honor of Eliza's patron the Viceroy of Mexico, Juan Vicente de Güemes, 2nd Count of Revillagigedo[1]
