The Anglican Church of Southern Africa, known until 2006 as the Church of the Province of Southern Africa, is the province of the Anglican Communion in the southern part of Africa. The church has twenty-five dioceses, of which twenty-one are located in South Africa, and one each in Eswatini, Lesotho, Namibia and Saint Helena.
The Anglican Church of Southern Africa claims 3–3.57 million members. In the 2001 South African Census, there were a recorded 1.7 million Anglicans out of a total South African population of close to 45 million.

The Anglican Church of Southern Africa estimated in 2006 that there were between 3 and 4 million Anglicans across Angola, Lesotho, Swaziland, Mozambique, Namibia, South Africa and the island of St Helena. A study published in 2020 produced an estimated figure of 2.3 million (4%) Anglicans in South Africa as of 2015. In 2021, the World Christian Database produced an estimated figure of 3,502,000 Anglicans or 6% of the population of South Africa as of 2020. Anglicans were estimated to make up around 167,388 people or 7.4% of the population of Lesotho in 2021. The Diocese of Swaziland had 90,000 members in 2021. In Namibia, 17% of the population, or 374,000 people, are Anglicans as of 2013. The majority of Saint Helena's population of 4,439 people are Anglicans.
