Commonwealth Bank Building, Gladstone, Heritage-listed bank building in Gladstone, Australia.

The Commonwealth Bank Building is a two-storeyed brick and concrete building with a sub-floor at 114 Goondoon Street, Gladstone. Built in 1928–29, it has a restrained Mediterranean style with a colonnaded entry porch, arched windows and a terracotta tiled roof. The ground floor held the banking chamber and the upper floor the manager's three-bedroom residence.

Built in 1928–29 for the Commonwealth Bank of Australia, the two-storey brick building held the ground-floor banking chamber and the manager's three-bedroom residence upstairs. It served as the bank's principal Gladstone branch until February 1972, when larger offices opened opposite. It was added to the Queensland Heritage Register on 28 July 2000.

The bank's Mediterranean styling, with a colonnaded entry porch, arched windows and a terracotta tiled roof, was chosen to project a modern, progressive image for money management. The manager lived in a three-bedroom residence on the upper floor, above the banking chamber with its three teller boxes.

The building is protected under heritage preservation laws that restrict any changes to its structure. Visitors should explore the exterior from street level to appreciate its architectural details.

The 1928 plans by the Commonwealth Department of Works and Railways specified a "Spanish style" brick building, part of a Mediterranean fashion the bank used to project a modern, reliable image. Tenders were called in September 1928 and the Gladstone contractor F. F. Hill won the job at £8,384.
