Bernardino Machado, Portuguese academic and politician, 3rd President of Portugal (b. 1851)
Bernardino Luís Machado Guimarães, GCTE, GCL (Portuguese pronunciation: [bɨɾnaɾˈdinu mɐˈʃadu]; 28 March 1851 – 29 April 1944), was a Portuguese political figure, the third and eighth President of Portugal (1915–17, 1925–26).

In 1917, Sidónio Pais, who was at the head of a military junta, dissolved Congress and removed Machado, forcing him to leave the country. Later, in 1925, he returned to the presidency of the Republic and, a year later, he was again overthrown by the military revolution of 28 May 1926, which instituted the military dictatorship and paved the way for the establishment of the Estado Novo.
