The Nammuldi mine is an iron ore mine located in the Pilbara region of Western Australia, 60 kilometres north-west of Tom Price.

The mine is fully owned and operated by Rio Tinto Iron Ore and is one of seventeen iron ore mines the company operates in the Pilbara. In 2009, the combined Pilbara operations produced 202 million tonnes of iron ore, a 15 percent increase from 2008. The Pilbara operations accounted for almost 13 percent of the world's 2009 iron ore production of 1.59 billion tonnes.

The Hamersley Range, where the mine is located, contains 80 percent of all identified iron ore reserves in Australia and is one of the world's major iron ore provinces.
