The Roman Catholic Diocese of Westminster is a diocese of the Latin Rite of the Roman Catholic Church in England. The diocese consists of all of London north of the River Thames and west of the River Lea, the borough of Spelthorne (in Surrey), and the county of Hertfordshire, which lies immediately to London's north.
The diocese is led by the Archbishop of Westminster, who serves as pastor of the mother church, Westminster Cathedral, as well as the metropolitan bishop of the ecclesiastical Province of Westminster. Since the re-establishment of the English Catholic dioceses in 1850, each Archbishop of Westminster—including the incumbent, Cardinal Vincent Gerard Nichols—has been created a cardinal by the Pope in consistory, often as the only cardinal in England, but the 43rd of English cardinals since the 12th century. It is also customary for the Archbishop of Westminster to be elected President of the Catholic Bishops' Conference of England and Wales providing a degree of a formal direction for the other English bishops and archbishops. However, he is not formally a primate, though he has special privileges conferred by the Papal Bull Si qua est. The 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 Roman 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 Diocese of Canterbury. 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 diocese 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)—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.
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. This followed Cardinal Murphy-O'Connor's announcement on 9 July 2007 that, in accordance with the age limit of 75 years prescribed for bishops in the Code of Canon Law, he had submitted his resignation to Pope Benedict XVI. He further announced that the Pope had asked him to continue in his pastoral ministry as archbishop beyond the age limit until further provision was made.
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.
Liturgy in the diocese is primarily based around the Revised Roman Rite promulgated by Pope Paul VI now in its third ion. However, as might be expected from a city as cosmopolitan as London, there is a great diversity in the liturgy as celebrated by Catholics. The Latin Mass Society arranges liturgy according to the 1962 Missal with episcopal approval. The Ukrainian Rite Catholics have a strong presence in the diocese with their own cathedral in Binney Street close to Bond Street. There is a Lebanese Maronite community based at Our Lady of Sorrows Catholic Church in Cirencester Street in West London; a Melkite community in Pimlico, at St Barnabas' Church of England church; an Ethiopian Catholic church, Our Lady Queen of Heaven, in Queensway West London; an Eritrean Catholic church, St Aidan of Lindisfarne, in East Acton; a Chaldean Catholic church, St Anne's, in Laxton Place and a Belarusian Catholic church in Holden Avenue in North London. There are also a large number of masses for the expatriate Polish community; as well as French, German, Spanish and Italian language churches.
The diocese is also responsible for many chaplaincies, including Heathrow Airport, hospitals and prisons. See St. George's Interdenominational Chapel, Heathrow Airport for more information about the Heathrow Airport Latin-rite Catholic chaplaincy.
There are a large number of religious communities in the diocese. Religious orders of men include: the Assumptionists at Bethnal Green, Hitchin and Burnt Oak; the Augustinians at Hammersmith and Hoxton; the Augustinian Recollects at Kensal New Town, Kensington and Wembley; the Benedictines at Ealing Abbey and Cockfosters; the Carmelites at Finchley East; Discalced Carmelites at Kensington; the Christian Brothers at Twickenham; the missionary Columban Fathers at Hampstead; the Dominicans at Haverstock Hill; the Franciscans at Pimlico; the Franciscan Friars of the Atonement in Westminster; the Holy Ghost Fathers at New Barnett and Northwood; and the Passionists at Highgate.

The Oratorians are based at the Church of the Immaculate Heart of Mary in Kensington, which is popularly known as the Brompton Oratory and is the largest church in the diocese after Westminster Cathedral.

The diocese is involved in both the independent and state school sectors. Some 159 state and 10 independent primary schools are run by the diocese along with 42 state and 4 independent secondary schools. There are also a further five independent primary / secondary and special schools including the Choristers school attached to the cathedral.
Music in the diocese is as diverse as the communities represented in it, but the all-male cathedral choir is reputedly one of the best in the country  and sings at all chief masses in the cathedral as well as the daily divine offices. There are several choirs that specialise in Gregorian Chant and a Charismatic group centred on the diocesan seminary at Allen Hall.
The diocese is divided into 24 deaneries and 217 parishes:
In London: 156 parishes
