George Musalas "Colvos" Colvocoresses (October 22, 1816 – June 3, 1872) was a United States Navy officer who commanded the Saratoga during the American Civil War. From 1838 up until 1842, he served in the United States Exploring Expedition, better known as the Wilkes Expedition, which explored large regions of the Pacific Ocean. Three separate geographical features, two on the west coast of the United States and another in Antarctica, were named for Colvocoresses.
