António Luís de Meneses, 1st Marquis of Marialva and 3rd Count of Cantanhede (13 December 1596 – 16 August 1675) was a member of the Forty Conspirators and a Portuguese general who fought in the Portuguese Restoration War, that ended the Iberian Union between Portugal and Spain.

Meneses was born in a noble family - his father was Dom Pedro de Menezes, 2nd count of Cantanhede, and his mother Dona Constança de Gusmão (daughter of Rui Gonçalves da Câmara, 1st count of Vila Franca).

In 1641 he was assigned as general-commander (mestre-de-campo) of the Portuguese forces loyal to John IV of Portugal, and he organized the defences against Spanish attacks.

After the success in the first battle the Count of Cantanhede received among several honors, the title of Marquis of Marialva on 11 June 1661.

After his victory at Montes Claros, he also worked to establish the Convent of São Pedro de Alcântara.
