The Archdiocese of Westminster (Latin: Archdioecesis Vestmonasteriensis) is a Latin archdiocese of the Catholic Church in England and Wales. Although a metropolitan archdiocese governed by an archbishop, it is usually referred to as the Diocese of Westminster. The archdiocese covers the historic counties of Hertfordshire and Middlesex.

The diocese is led by the Archbishop of Westminster, who serves as pastor of Westminster Cathedral, as well as the metropolitan bishop of the Province of Westminster. Since the re-establishment of the English Catholic dioceses in 1850, each archbishop of Westminster—including the most recent, Cardinal Vincent Nichols—has been created a cardinal by the pope in consistory, often as the only cardinal in England, and is now the 43rd of English cardinals since the 12th century. It is also customary for the metropolitan archbishop of Westminster to be selected president of the Catholic Bishops' Conference of England and Wales providing a degree of a formal direction for the other English bishops and archbishops. Though not formally a primate, he has special privileges conferred by the papal bull Si qua est. The metropolitan archbishop of Westminster has not been granted the title of Primate of England and Wales, which is sometimes applied to him, but his position has been described as that of "chief metropolitan" of the Catholic Church in England and Wales and as "similar to" that of the archbishop of Canterbury in the Church of England (as the metropolitan bishop of the Province of Canterbury)."As ordinary of the Diocese of Westminster his jurisdiction extends over much the same area as that of the Bishop of London. As chief metropolitan, he occupies a position similar to that of the Archbishop of Canterbury, Primate of All England" ().

"By the grant in the Apostolic Constitution of 'certain new distinctions of preeminence', for the preservation of unity in government and policy, to the archbishop of Westminster for the time being, comprised under the following three heads: He will be permanent chairman of the meetings of the Bishops of all England and Wales, and for this reason it will be for him to summon these meetings and to preside over them, according to the rules in force in Italy and elsewhere. (2) He will take rank above the other two Archbishops, and will throughout all England and Wales enjoy the privilege of wearing the Pallium, of occupying the throne, and of having the cross borne before him. (3) Lastly, in all dealings with the Supreme Civil Authority, he will in his person represent the entire Episcopate of England and Wales. Always, however, he is to take the opinion of all the Bishops, and to be guided by the votes of the major part of them'. Thus, though the Archbishop of Westminster was vested with more powers and privileges than primates usually enjoy, unity of action has been safeguarded" (). The diocese is one of the smallest dioceses in England and Wales in geographical area, but the largest in terms of Catholic population and priests.

The suffragan sees of Westminster are the dioceses of Brentwood, East Anglia, Northampton, and Nottingham.

History The archdiocese essentially covers the same region as the Church of England Diocese of London as it was before the English Reformation until 1850, adopting—like all other dioceses across England (created that year)The Anglican Diocese of Liverpool was not created until 1880, thirty years after the Roman Catholic Diocese (now Archdiocese) of Liverpool was established.—an alternative name (originally because of the Ecclesiastical Titles Act 1851) but based on the centuries-old divisions of the country. The diocese effectively survived the period of Catholic oppression in English history as a missionary territory established by canons accepted by Rome in 1622 as the Apostolic Vicariate of England which was in public law pronounced in England and Wales illegal as counter to the established church.

The mostly clandestine apostolic vicariate covering the country was divided so that the Apostolic Vicariate of London District formed on 30 January 1688 coinciding with a degree of freedoms. By decree of Pope Pius IX (Universalis Ecclesiae), this entity gained its elevation to the rank of a metropolitan diocese (instead of archdiocese) on 29 September 1850.

Present On 3 April 2009, it was announced that the Archbishop of Birmingham, the Most Reverend Vincent Nichols, would become the 11th Archbishop of Westminster. Cormac Murphy-O'Connor, who was installed as tenth Archbishop of Westminster on 22 March 2000 and was elevated to the rank of cardinal-priest of the title of Santa Maria Sopra Minerva by Pope John Paul II on 21 February 2001, became archbishop emeritus. Cardinal Murphy-O'Connor had announced on 9 July 2007 that, in accordance with the age limit of 75 years prescribed for bishops in the 1983 Code of Canon Law, he had submitted his resignation to Pope Benedict XVI, but that the Pope had asked him to continue in his pastoral ministry as archbishop beyond the age limit until further provision was made, as occurred in 2009.

The archbishop is usually assisted by four auxiliary bishops, each with specific areas of responsibility within the administration of the diocese. One of the auxiliary bishops serves as chancellor and moderator of the metropolitan curia; one as vicar for the clergy; one for pastoral affairs; and one for education and formation.

The metropolitan curia and chancery offices are located at Vaughan House, outside Westminster Cathedral in central London. The diocesan seminary, Allen Hall, is located in Chelsea, West London, and (with Ushaw College) is a direct descendant of the seminary of Douai College, France.

The Diocese is a registered charity No. 233699.
