The North Pacific Exploring and Surveying Expedition, also known as the Rodgers-Ringgold Expedition was a United States scientific and exploring project from 1853 to 1856.
Commander Cadwalader Ringgold (1802–1867) led the expedition until he was relieved of command in Hong Kong by a commission convened by Commodore Matthew Perry. Lt. John Rodgers (1812–1882) then commanded the expedition until its conclusion.
