Alfredo Jorge Nobre da Costa, (10 September 1923 – 1 April 1996), commonly known as Nobre da Costa (pronounced as /pt/), was a Portuguese engineer and politician who briefly served as prime minister of Portugal from August to November 1978.
A moderate independent center-left politician, he was appointed by President António Ramalho Eanes to serve as prime minister that would finish the four-year legislative term which had been initiated in the 1976 Portuguese legislative election. His cabinet consisted of independents. However, it failed to gain a majority in the Assembly of the Republic, and Nobre da Costa resigned. He was replaced by Carlos Alberto da Mota Pinto.
He was the only son of Alfredo Henrique Andresen da Costa (born 4 November 1893), who was Portuguese of Italian, French, Danish and Goan ancestry, and Maria Helena Nobre.
He graduated from Instituto Superior Técnico.
He married Maria de Lourdes de Carvalho e Cunha Fortes da Gama on 5 May 1951 and had a single daughter, Vera Maria Nobre da Costa (born 5 February 1952). He died in 1996 after a long illness. At the time of his death he held the position of chairman at the engineering firm EFACEC.[2]
