Cormac Murphy-O'Connor, (born 24 August 1932) is a Cardinal of the Roman Catholic Church, Archbishop Emeritus of Westminster and former President of the Catholic Bishops' Conference of England and Wales. He was created a cardinal by Pope John Paul II in the 2001 Consistory. His resignation was submitted upon reaching his 75th birthday and was accepted on 3 April 2009 when Pope Benedict appointed Vincent Nichols as the new Archbishop.

By virtue of his position as Archbishop of Westminster, he was sometimes referred to as the Catholic Primate of England and Wales. However, though the holders, within the Church of England, of the posts of Archbishop of Canterbury and Archbishop of York are called, respectively, "Primate of All England" and "Primate of England", the title of primate has not been accorded to the leader of the Catholic Church in England and Wales.

Cormac Murphy-O'Connor was born in Reading, Berkshire, the fifth son of George and Ellen Murphy-O'Connor, who emigrated from County Cork in Ireland before World War I and married in 1921. Two of his uncles, one aunt, two cousins, and two of his brothers, Brian and Patrick, also entered religion. His youngest brother, John, was a regular officer in the Royal Artillery who died at age 32 for reasons which have never been clarified; he has two other siblings, James (a doctor and rugby player) and Catherine. After attending Presentation College in Reading, and Prior Park College in Bath, Murphy-O'Connor then began his studies for the priesthood in 1950 at the Venerable English College in Rome, where he received a degree in theology. Thereafter, he earned a licentiate in philosophy and a licentiate in sacred theology from the Pontifical Gregorian University. He was ordained on 28 October 1956, by Valerio Cardinal Valeri. For the next decade he did pastoral work in Portsmouth and Fareham.
