USS Oneota was a single-turreted Canonicus-class monitor built for the Union Navy during the American Civil War. Completed shortly after the end of the war, Oneota was laid up until sold to her builders in 1868, and then resold to the Peruvian Navy. Renamed BAP Manco Cápac, the ship participated in the defense of Arica during the War of the Pacific. When the town was taken by Chilean troops in 1880, she was scuttled to prevent her capture. Her wreck was rediscovered in 1960 and it has been heavily looted.
