The Gold Creek Dam is an earth-fill embankment dam with an un-gated spillway across the Gold Creek that is located in the South East region of Queensland, Australia. The main purpose of the dam is for potable water supply of the Brisbane region. The resultant reservoir is called the Gold Creek Reservoir.

The Gold Creek Dam is located on the edge of Brisbane Forest Park, 14 kilometres (8.7 mi) west of Brisbane, on the Gold Creek, a tributary of Moggill Creek, to augment supplies from the recently completed Enoggera Dam. Unlike Enoggera, the Gold Creek site could supply water to the most elevated parts of the city.

The earthfill dam structure is 26 metres (85 ft) high and 475 metres (1,558 ft) long. The 106-thousand-cubic-metre (3.7×10^⁶ cu ft) dam wall holds back the 801-megalitre (176×10^⁶ imp gal; 212×10^⁶ US gal) reservoir when at full capacity. From a catchment area of 10.5 square kilometres (4.1 sq mi), the dam creates an unnamed reservoir with an average depth of 26 metres (85 ft). The surface area of the 1.2-metre (3 ft 11 in) wide reservoir is 2.46 hectares (6.1 acres). The uncontrolled un-gated spillway has a discharge capacity of 132 cubic metres per second (4,700 cu ft/s). Initially managed by the Brisbane City Council up until 2008, the dam is now managed by Seqwater.
