Infante Alexandre of Portugal (Alexandre Francisco José António Nicolau; English: Alexander Francis Joseph Anthony Nicholas, 24 September 1723 - 2 August 1728) was a Portuguese infante, the sixth and last child of King John V of Portugal and his wife Maria Anna of Austria.[1]


Born on 24 September 1723 in the Ribeira Palace, in Lisbon, the infante was baptized on 6 December as Alexandre Francisco José António Nicolau de Bragança.[2]

In his short life, he revealed an advanced intelligence for his age, through his prompt and ingenious observations, as described by the genealogist António Caetano de Sousa.[2]

He died in the same Palace where he was born on 2 August 1728, at the age of 4, victim of smallpox. He is buried in the Royal Pantheon of the House of Braganza.[2]
