Manuel Gonçalves Cerejeira, GCC, GCSE, GCIH (29 November 1888, Lousado, Vila Nova de Famalicão, Portugal – 2 August 1977, Buraca, Amadora, Portugal) was a Portuguese cardinal who served as Patriarch of Lisbon from 1929 to 1971.
He was the last surviving cardinal elevated by Pope Pius XI, and his cardinalate of forty-eight years was the longest since the fifty-eight-year cardinalate of Henry Benedict Mary Clement Stuart of York which lasted from 1747 to 1805.
He took part in three conclaves: in 1939, 1958 and 1963.
Although there were seven other cardinals elevated by Pius XI who participated in the 1963 conclave, Cerejeira was the longest-serving living cardinal from the death of Jozef-Ernest van Roey on 6 August 1961 until his own death almost exactly sixteen years later.
