Rio Tinto Group is a British-Australian multinational mining company headquartered in London, England, and Melbourne, Australia. It was founded in 1873 when a group of British investors purchased a mine complex on the Río Tinto, in Huelva, Spain, from the Spanish government. It has grown through a long series of mergers and acquisitions and is today a major producer of commodities such as copper, iron ore, aluminium and lithium.
Rio Tinto is a dual-listed company, traded on both the London Stock Exchange, where it is a component of the FTSE 100 Index, and the Australian Securities Exchange, where it is a component of the S&P/ASX 200 index. American depositary shares of Rio Tinto's British branch are also traded on the New York Stock Exchange, giving it listings on three major stock exchanges. In the 2020 Forbes Global 2000, it was ranked the world's 114th-largest public company. It was ranked the world's 274th largest company in the 2025 Fortune Global 500.
Rio Tinto has faced criticism by environmental groups as well as the government of Norway for the environmental impacts of its mining activities.
