Artur de Sacadura Freire Cabral, GCTE (23 May 1881 – 15 November 1924), known simply as Sacadura Cabral (Portuguese pronunciation: [s?k?'du?? k?'b?a?]), was a Portuguese aviation pioneer.
He, together with fellow aviator Gago Coutinho, conducted the first flight across the South Atlantic Ocean in 1922, and also the first using only astronomical navigation, from Lisbon, Portugal, to Rio de Janeiro, Brazil.
Although some mechanical wreckage from his seaplane was discovered four days later, the bodies were never recovered.
A statue dedicated to them is located in Lisbon.
Another statue is located in his hometown, Celorico da Beira.
He was the granduncle of Portuguese politicians Miguel Portas and Paulo Portas.
