Francisco Joaquim Ferreira do Amaral, GCTS, KCVO (Lisbon, Santa Catarina, 11 June 1843 - 11 August 1923) was a Portuguese naval commander and politician.
He distinguished himself as a military and became Vice-Admiral and Admiral of the Portuguese Navy, being able to conquer important territories in Cabinda, Angola. For his successes, the realm wanted to grant him the title of Count, which he refused, suggesting that it would be better to grant his mother instead, who would be happier with it.
