Manuel de Oliveira Gomes da Costa, Portuguese general and politician, 10th President of Portugal (d. 1929)
Manuel de Oliveira Gomes da Costa , commonly known as Manuel Gomes da Costa (Portuguese pronunciation: [mɐnuˈɛɫ ˈɡomɨʒ dɐ ˈkɔʃtɐ]) or just Gomes da Costa (14 January 1863 – 17 December 1929), was a Portuguese army officer and politician, the tenth President of the Portuguese Republic and the second of the National Dictatorship.

Gomes da Costa had a distinguished military career in the country's colonies, from 1893 to 1915, in India, Mozambique, Angola, and São Tomé, having served under the command of Mouzinho de Albuquerque. After World War I, in which he rose to greater prominence in the command of the 1st Division of the Portuguese Expeditionary Corps, he became actively engaged in politics, in staunch opposition to the dominant Democratic Party.

In 1926, he was involved in the military and political movement that resulted in the 28 May 1926 coup d'état that inaugurated a new conservative, authoritarian regime. Following the military coup, Gomes da Costa deposed moderate José Mendes Cabeçadas, who had received executive and presidential power from the removed Prime Minister António Maria da Silva and President Bernardino Machado, briefly holding the headship of government and of state in the summer of that year, until he was himself removed by another coup, to be replaced by Óscar Carmona.
