Quinsigamond was a Kalamazoo-class double-turreted monitor, designed by Benjamin F. Delano. Quinsigamond was laid down by the Boston Navy Yard in 1864, but work on her was suspended on 30 November 1865 following the end of the American Civil War. Renamed Hercules on 15 June 1869, she was again renamed, Oregon on 10 August the same year. Designed to be built at naval yards, which lacked the facilities to construct metal-ribbed vessels, she was built with improperly seasoned timber, and left exposed to the elements. Quinsigamond's hull began to rot while still on the stocks and she was broken up in 1884.
