Antônio Hamilton Martins Mourão (Portuguese pronunciation: [ɐ̃ˈtõniu ɐˈmiwtõ maʁˈtʃĩz mowˈɾɐ̃w]; born 15 August 1953) is a Brazilian politician and retired military officer who served as the 25th vice president of Brazil from 2019 to 2023.

[1] During his tenure in the military, he became nationally-known after a 2015 incident in which he criticized then-President Dilma Rousseff and called for "the awakening of a patriotic struggle".

[12][13][14] Bolsonaro did not choose Mourão as his running mate in the 2022 election, instead picking Walter Souza Braga Netto in a losing presidential bid.

[15] Mourão opted instead to run for the Senate in the 2022 Brazilian general election, representing the state of Rio Grande do Sul, which he won.

[20][21] Mourão joined the Brazilian Army in February 1972, in the Academia Militar das Agulhas Negras (AMAN), in Resende, Rio de Janeiro, where he became on officer on December 12, 1975.

As lieutenant, he was instructor at Military Academy and as Captain, he worked with Jair Bolsonaro in the 8th Paratrooper Field Artillery Group, placed in Rio de Janeiro.

He commanded the 27th Field Artillery Group in Ijuí, Rio Grande do Sul; the 2nd Jungle Infantry Brigade in São Gabriel da Cachoeira, Amazonas; the 6th Army Division and Military Command of the South in Porto Alegre, Rio Grande do Sul.

In a public announcement of the Masonic Lodge Grande Oriente in September 2017, in the Federal District, Mourão stated that, "among the duties of the Brazilian Army, there was the guarantee of the operation of the institutions and of the law and order", and that, if the judiciary "couldn't be able to heal the existing politics in the country, this would be imposed by the army through a military intervention", which, in his vision, "is provided by the Federal Constitution of 1988".

He also called the Unified Federation of Oil Workers' strike, "shameful", and said "there are people taking advantage [of the situation] on both sides".

[24] On 8 May 2018, Mourão announced his membership in the Brazilian Labor Renewal Party (PRTB) and his intention to run for President of Brazil, along with Levy Fidelix.

[26] On 28 October 2018, Jair Bolsonaro won 55.2% of the vote against 44.8% for Fernando Haddad of the left-wing Workers' Party in the Brazilian presidential election.

[29] In February 2022, Mourão was disauthorized by Brazilian President Jair Bolsonaro for saying that Brazil opposed the Russian invasion of Ukraine.

[30] In March 2022, Mourão changed his political affiliation to Republicanos, declaring his intention to run for the Senate in the 2022 Brazilian general election, representing the state of Rio Grande do Sul.

[32] In the 2022 Brazilian general election, Mourão ran for Senate to representing the state of Rio Grande do Sul as a member of the Republicanos party.
