Christ Church Cathedral, Newcastle, Anglican cathedral in Newcastle, Australia

Christ Church Cathedral is an Anglican cathedral in Newcastle with Gothic Revival architecture, featuring intricate stone carvings and stained glass windows throughout. The building displays the craftsmanship and decorative details typical of this architectural style in its interior spaces and exterior form.

John Horbury Hunt designed the cathedral in 1868, but construction only began in 1883 after earlier plans by Terry and Speechly proved too costly. The original Christ Church, built in 1817–18, stayed in use until its staged demolition in 1884. The cathedral was dedicated in 1902, and the tower was added in 1979 without the spire Hunt had intended.

The cathedral is the seat of the Bishop of Newcastle, a diocese created in 1847 when Newcastle became a city. The first dean of the new foundation, William Tyrrell, was appointed bishop in 1848. Since October 2017 the Dean has been Katherine Bowyer, the first woman to hold the post.

The cathedral stands on a hill at the eastern end of the city centre, in the suburb of The Hill, so the walk up from the harbour is steep. Entry is through the arcaded base beneath the tower; the lawn inside the low wall is the only level ground nearby. The 1989 earthquake repairs left the 1817 foundation stone reset inside the building, near its original position.

The 1817 foundation stone of the earlier Christ Church was repositioned inside the cathedral during repairs after the 1989 earthquake, placed as close as possible to its original spot. The cathedral's brickwork survived that quake largely because Hunt insisted on tight, mortar-filled perpends in the walls.
