The Mohongo-class gunboat were a series of seven side-wheel double-ended gunboats operated by the United States Navy during the late 19th century. The ships were built for the Union Navy during the American Civil War and was the third generation of double-ended gunboats intended to engage Confederates in rivers and shallow water. Only one ship was completed in time to join the war effort. By 1870, four ships were sold for civilian use and an additional gunboat was wrecked. The two remaining ships, Monocacy and Ashuelot, were assigned to the Asiatic Squadron. Ashuelot was wrecked in 1883 and Monocacy was retired and replaced in 1903.
