António Alva Rosa Coutinho (14 February 1926 – 2 June 2010) was a Portuguese admiral, political activist, and participant in the Carnation Revolution.

[3] During the Carnation Revolution (25 April 1974) he was one of the officers who made up the Junta de Salvação Nacional (JSN), and was subsequently promoted from captain to vice-admiral.

Coutinho defended the territorial integrity of Angola against the Zairean-backed Front for the Liberation of the Enclave of Cabinda, and openly distributed Portuguese arms and equipment to the MPLA.

In the early part of 1975 he began to advocate the passage of "revolutionary laws" with the aim of radicalizing the political process that had been initiated by the Carnation Revolution.

Though he no longer exerted much influence in politics, he remained involved in the Angolan solidarity movement and continued to campaign in support of Portuguese left-wing parties.
