Joaquim José Inácio, Viscount of Inhaúma (Portuguese: [iɲaˈũmɐ]; 1 August 1808 – 8 March 1869), was a naval officer, politician and monarchist of the Empire of Brazil. He was born in the Kingdom of Portugal, and his family moved to Brazil two years later. After Brazilian independence in 1822, Inhaúma enlisted in the Brazilian navy. Early in his career during the latter half of the 1820s, he participated in the subduing of secessionist rebellions: first the Confederation of the Equator, and then the Cisplatine War, which precipitated a long international armed conflict with the United Provinces of the River Plate.
