The Port Augusta Town Hall is a heritage-listed former town hall at 54 Commercial Road, Port Augusta. It was added to the South Australian Heritage Register on 23 September 1982; it was also listed on the now-defunct Register of the National Estate. In 1983, the City of Port Augusta vacated the building when the new Port Augusta Civic Centre was completed. It was subsequently used by community groups for many years, but much of the building remained disused and it became increasingly derelict over time. In 2007, a teenage boy was injured after falling through the building's roof.
