The ordination of women in the Anglican Communion has been increasingly common in certain provinces since the 1970s. Several provinces, however, and certain dioceses within otherwise ordaining provinces, continue to ordain only men. Disputes over the ordination of women have contributed to the establishment and growth of progressive tendencies, such as the Anglican realignment and Continuing Anglican movements.

The Anglican Communion is the third largest Christian communion after the Roman Catholic and Eastern Orthodox churches. Formally founded in 1867 in London, the communion has more than 85 million members within the Church of England and other autocephalous national and regional churches in full communion. The traditional origins of Anglican doctrine are summarised in the Thirty-nine Articles (1571). The archbishop of Canterbury in England acts as a focus of unity, recognised as primus inter pares, but does not exercise authority in Anglican provinces outside of the Church of England. Most, but not all, member churches of the communion are the historic national or regional Anglican churches.
