USS Severn was a Contoocook-class frigate of the United States Navy. She was laid down as Mosholu during the American Civil War to deter British intervention in 1864, although timber shortages and a rushed construction delayed progress. While intended as a sloop, modifications while under construction enlarged her armament and converted her into a frigate. Renamed and launched in 1869, her design was criticized and green wood limited her service life. After a brief two-year stint in the Atlantic and Caribbean, she was decommissioned in 1871. In 1877, she was sold and broken up as part of a scheme to fund the construction of USS Puritan.
