St James' Church, commonly known as St James', King Street, is an Australian heritage-listed Anglican parish church located at 173 King Street, in the Sydney central business district in New South Wales. Consecrated in February 1824 and named in honour of St James the Great, it became a parish church in 1835. Designed in the style of a Georgian town church by the transported convict architect Francis Greenway during the governorship of Lachlan Macquarie, St James' is part of the historical precinct of Macquarie Street which includes other early colonial era buildings such as the World Heritage listed Hyde Park Barracks.

The Anglican Church of Australia, formerly known as the Church of England in Australia and Tasmania, is a Christian church in Australia and an autonomous church of the Anglican Communion. It is the second largest church in Australia after the Catholic Church. According to the 2016 census, 3.1 million Australians identify as Anglicans. As of 2016, the Anglican Church of Australia had more than 3 million nominal members and 437,880 active baptised members. For much of Australian history since the arrival of the First Fleet in January 1788, the church was the largest religious denomination. It remains today one of the largest providers of social welfare services in Australia.
