Felisberto Caldeira Brant Pontes de Oliveira Horta, the Marquis of Barbacena (19 September 1772 – 13 June 1842) was a Brazilian soldier and statesman of both Portugal and the Empire of Brazil.

Early in his career, Brant was sent to Angola, where he served as aide de camp to the royal governor there.

In 1807, during the French invasion of Portugal, the Prince Regent, Dom João VI, fled to Brazil with a large retinue.

There, he became a pioneer in the field of steam transportation, developing such an interest in the method that he was granted official authorization to study it.

Brant supported Dom Pedro, now the Emperor, being sent on a diplomatic mission to London by José Bonifácio, the minister for both internal and foreign affairs.
