The Fimiston Open Pit, colloquially known as the Super Pit, was Australia's largest open cut gold mine until 2016 when it was surpassed by the Newmont Boddington gold mine also in Western Australia. The Super Pit is located off the Goldfields Highway on the south-east edge of Kalgoorlie, Western Australia. The pit is oblong in plan view and is approximately 3.5 kilometres long, 1.5 kilometres wide and over 600 metres deep.

The Fimiston Open Pit is owned by Northern Star Resources. The mine produced 456,000 troy ounces (14.2 t) of gold in 2019, and employs around 1,100 employees and contractors directly on site.
