The Mariz e Barros-class ironclads were a pair of armored corvettes originally ordered by Paraguay in 1864, but were sold to Brazil when Paraguay defaulted on the payments. Configured as central-battery ironclads, they served during the 1864–70 Paraguayan War between Brazil, Argentina and Uruguay against Paraguay. They were named after Antônio Carlos de Mariz e Barros (1835–1866), son of Joaquim José Inácio, Viscount of Inhaúma, Brazilian military officer and hero of the Paraguayan War.
