The Brazilian ironclad Tamandaré was an armored gunboat built for the Brazilian Navy during the Paraguayan War in the mid-1860s. She bombarded the Paraguayan fortifications blocking access up the Paraná and Paraguay Rivers as well as bombarding Paraguayan positions in support of the Brazilian Army. The ship participated in the Passagem de Humaitá in February 1868 and was badly damaged. After Tamandaré was repaired she provided fire support for the army for the rest of the war, aside from bombarding Paraguyan capital of Asunción once. The ship was assigned to the Mato Grosso Flotilla after the war. Tamandaré was decommissioned in 1879 and scrapped afterwards.
