Constituição was a frigate of the Imperial Brazilian Navy.

Design and construction
On 21 January 1824, emperor Pedro I of Brazil appointed José Silvestre Rebelo as Brazil's chargé d'affaires to the United States. Rebelo received instructions from, then Minister of Foreigners, to negotiate the acquisition of frigates and other ships in the United States, being advised to await further "special instructions, which would be given at the appropriate time, reached by agreement with the naval officer specially designated for that purpose and who would be the bearer of those instructions". Rebelo arrived in Baltimore on 26 March 1824, being received by president James Monroe.

On 24 September 1824, the Brazilian government issued a note ordering the construction of two war frigates, designating lieutenant-captain José Joaquim Faustino to direct and inspect the construction of the ships with master carpenter José Rodrigues Bairão, from the Court's Navy Arsenal, as his assistant. On 3 January 1825, Rebelo concluded the contract with shipbuilder Henry Eckford for the construction of two frigates "in every way similar to those of the United States war navy". The frigates should be delivered on 1 May 1826 for the price of 350 thousand pesos each, but without any guns, ammunition and gunpowder.

The Brazilian government deemed the price too high, to which Rebelo argued that "if a 50-gun frigate costs 500 thousand cruzados in Rio de Janeiro and a 74-gun ship a million, it was clear that a 62-gun one could not cost less than 750 thousand cruzados".
