The Diocese of Pretoria is a diocese of the Anglican Church of Southern Africa. It is divided into seven archdeaconries and has 61 parishes.

The diocese originally covered the whole of the South African Republic, which later became the Transvaal province of South Africa. In 1922 the Diocese of Johannesburg, covering the Southern Transvaal, was formed. In the 1980s and 1990s several new dioceses were formed.

The northernmost part of the diocese covered what is today the Limpopo Province. Suffragan Bishops were often based at Christ Church, Polokwane (then, Pietersburg) to oversee the mission work of the church. In 1957 Bishop Robert Selby Taylor decided to make Pietersburg the centre of the Archdeaconry of the North. In the 1980s a suffragan bishop, John Ruston, was sent to oversee the region. Under his leadership a new diocese was formed. The Anglican Diocese of St Mark the Evangelist was inaugurated in 1987.

The diocese assumed arms around the time of its inception : Per fess Gules and Azure, a fess Argent between in chief a lion passant Or supporting a staff proper flying therefrom the banner of St George, and in base an anchor erect Or.

By 1889, the diocese had added a green border to the arms, possibly to reflect the colours of the South African Republic's national flag. It removed the border after the republic had become a British colony again in 1902, and changed the upper half of the shield to blue. In this form, the arms were granted by the College of Arms in 1954, and registered at the Bureau of Heraldry in 1964.^[5]
