The National Seal of Brazil (Portuguese: Selo Nacional do Brasil) is one of Brazil's national symbols, displayed on several official documents, such as graduation diplomas, consular and diplomatic papers, military conscription forms, etc.

This was packed in a wrapper and commonly made with sayings in Latin or in Portuguese about the Emperor, for example: “Pedro II, Constitutional Emperor of Brazil” or “Pedro II, Perpetual Defender of Brazil”.

The seal of the Imperial era was created by the ministerial notice signed by Luís Pereira da Nóbrega de Sousa Coutinho on October 24, 1822.

[1] The design of the National Seal is also represented on the reverse side of the Great Seal of the Arms of the Federative Republic of Brazil (that bears the image of the country's coat of arms on the obverse side), and is used by the Presidency of the Republic to authenticate solemn documents together with the President's signature, such as instruments of ratification of international treaties.

The wax or printed impression of the National Seal is also used to authenticate the original version of Laws promulgated by the President of Brazil.
