The AGO C.II was a German reconnaissance biplane of World War I. It was essentially a slightly redesigned version of the manufacturer's C.I design with a more powerful engine and 3-bay wings.
Two examples were equipped with floats (designation C.II-W) and operated by the Imperial German Navy for coastal patrol.
