Port Adelaide Uniting Church, Church building in Port Adelaide, South Australia, Australia

Port Adelaide Uniting Church is a church building on Port Adelaide's St Vincent Street, designed by James Macgeorge and built in 1867–1868 from Dry Creek sandstone with elaborate brickwork. Its Gothic interior seats 500 under a high ceiling, with a large rear gallery and a restored original pipe organ at the front. The tower and spire in Macgeorge's design were never built.

The congregation began in 1849 as the Congregational Church of Port Adelaide, meeting in a sail loft under Rev. Matthew Hodge. It used three buildings before the present church was built in 1867–1868 to James Macgeorge's design. In 1978 it joined the Uniting Church in Australia.

The church serves as a community gathering place and shapes the streetscape with its distinctive sandstone facade. Visitors regularly see people gathering for worship and notice how it reflects the religious identity of the port neighborhood.

Visitors can view the building during worship services and should expect authentic Gothic architecture and historical details throughout the interior. The location is best reached on foot and sits centrally in the port neighborhood with straightforward access from the main streets.

James Macgeorge drew a tower and spire for the church, but neither was ever built, so the 1867-68 building stands without them. The walls are Dry Creek sandstone laid with very elaborate brickwork, a detail easy to miss at street level. Since 1998 the church has been listed on the South Australian Heritage Register.
