Sir Vivian Ernest Fuchs was an English scientist-explorer and expedition organizer. He led the Commonwealth Trans-Antarctic Expedition which reached the South Pole overland in 1958.

The Commonwealth Trans-Antarctic Expedition (CTAE) of 1955–1958 was a Commonwealth-sponsored expedition that successfully completed the first overland crossing of Antarctica, via the South Pole. It was the first expedition to reach the South Pole overland for 46 years, preceded only by Amundsen's expedition and Scott's expedition in 1911 and 1912.
