St James' Church, commonly known as St James', King Street, is an Anglican parish church in inner city Sydney, Australia, 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 Hyde Park Barracks. The church building is the oldest one extant in Sydney's inner city region.
