Captain George Vancouver (22 June 1757 10 May 1798) was a British officer of the Royal Navy best known for his 179195 expedition, which explored and charted North America's northwestern Pacific Coast regions, including the coasts of what are now the Canadian province of British Columbia as well as the US states of Alaska, Washington and Oregon. He also explored the Hawaiian Islands and the southwest coast of Australia.

Vancouver Island, the city of Vancouver in British Columbia, as well as Vancouver, Washington in the United States, are all named for him. Mount Vancouver, on the CanadianUS border between Yukon and Alaska, and New Zealand's sixth-highest mountain, also Mount Vancouver, are also named for him.
