Nereu de Oliveira Ramos (Portuguese pronunciation: [neˈɾew dʒi oliˈvejɾɐ ˈʁɐ̃mus]; 3 September 1888 – 16 June 1958) was a Brazilian political figure.

Army Minister Henrique Teixeira Lott subscribed to that view, and he considered that President Café Filho had taken his leave of absence because he was in agreement with the supposed coup forces but unwilling to lead the coup himself.

Thus, only 48 hours after Café Filho's declaration of incapacity and the assumption of the powers of the presidency by Carlos Luz, Army Minister Lott led what he called a preventive counter-coup aimed at securing the inauguration of the President–elect chosen by the people, by avoiding the supposed coup that Luz would allegedly lead.

In that preventive counter-coup, Luz was deposed, Café Filho was prohibited from resuming the powers and duties of the presidency (although he was not deposed, he was kept under house arrest for the remaining three months of his presidential term, and was barred from declaring his incapacity terminated), and the next man in the line of presidential succession, Senator Nereu Ramos, the Senate's President pro tempore assumed the powers of the presidency in the place of Carlos Luz.

Nereu Ramos died in a Cruzeiro airline crash on 16 June 1958, near Curitiba Afonso Pena International Airport.
