Coopers Gap Wind Farm is a 453 megawatt wind farm in the Western Downs and South Burnett regions of Queensland, Australia. It is located approximately 175 km north-west of the state capital Brisbane, and 50 kilometres south-west of Kingaroy and 65 kilometers north of Dalby. When construction was announced to be completed on 30 April 2020, it became the largest wind farm in Australia. This record was held until 10 December 2020 when the Stockyard Hill Wind Farm in Victoria was completed.

The wind farm is located in a hilly area, approximately 5 km to the north-west of the Bunya Mountains. It is located approximately 175 km (109 mi) north-west of the state capital Brisbane, and 50 km (31 mi) south-west of Kingaroy and 65 km (40 mi) north of Dalby.

The area is mostly cleared, cattle-grazing country and was originally planned to cover approximately 12,000 hectares (29,700 acres) in total, however the site area was reduced later in the development process to 10,200 hectares (25,200 acres). The site has an elevation of 535 to 840m. The project falls within both the South Burnett Regional Council and Western Downs Regional Council jurisdictions.

The side was identified by Windlab using their proprietary WindScape wind mapping technology in late 2005, and a 60-metre wind-monitoring mast was installed in March 2006 in order to accurately measure wind speed and direction in the area. After twelve months of data capture, the proponents began securing land and pre-feasibility studies started.

In 2009, development approval was expected in the same year.

In April 2011, some local landholders expressed concerns at a community forum related to health effects and the noise of the wind turbines, some of which would be less than a kilometre from homes.

In March 2017, the project was approved by the Coordinator-General. The approved project consisted of up to 115 turbines, with a maximum tip height of 180m, and a maximum rotor diameter of 140m.

The first turbine generated electricity to the grid on 24 June 2019.
