The Brazilian ironclad Barroso was an armoured gunboat built for the Brazilian Navy during the Paraguayan War in the mid-1860s. Barroso bombarded Paraguayan fortifications in 1866 and 1867 a number of times before she participated in the Passagem de Humaitá in February 1868. Afterwards the ship provided fire support for the army for the rest of the war. She was assigned to the Mato Grosso Flotilla after the war. Barroso was decommissioned in 1882, but was not scrapped until 1937.
