USS Tonawanda was one of four Miantonomoh-class monitors built for the United States Navy during the American Civil War of 1861–1865. Commissioned in 1865 after the war ended in May, the ship was decommissioned at the end of the year, but was reactivated to serve as a training ship at the United States Naval Academy in 1866. She was renamed Amphitrite in 1869 and was decommissioned again in 1872. The monitor was sold for scrap the following year. The Navy Department evaded the Congressional refusal to order new ships by claiming that the Civil War-era ship was being repaired while building a new monitor of the same name.
