José da Silva Lisboa, first Baron and Viscount of Cairu (July 16, 1756 in Salvador – August 20, 1835 in Rio de Janeiro), was an economist, historian, jurist, publicist and Brazilian politician, active at the time of Independence of the Brazil and credited for the promotion of important economic reforms.
He held various positions in the economic and political administration of Brazil after the transfer or the Portuguese Court to Brazil in 1808, including Deputy of the Royal Chamber of Commerce (Junta do Comércio) and Judge of the House of Supplication (Casa da Suplicação - a court of appeal).
Cairu played an important role in encouraging the teaching of political economy in the country, and participated actively in the drafting of the decrees that determined the opening of Brazilian ports (ending the Exclusive Metropolitan Trade, by which Brazil could only trade with Portugal) and the end of the prohibition of manufactures in Brazil.
His attitude favorable to the economic development of the United Kingdom of Brazil would end up contributing significantly to the conditions indispensable to the political independence of Brazil in 1822.
For his contributions, the Viscount of Cairu figures "with place of honor in the pantheon of the heroes of the Brazilian homeland".
