BHP (formerly known as BHP Billiton) is an Australian multinational mining, metals, and petroleum public company that is headquartered in Melbourne, Victoria, Australia.

BHP Billiton was formed in 2001 through the merger of the Australian Broken Hill Proprietary Company Limited (BHP) and the Anglo–Dutch Billiton plc trading on both the Australian and London Stock Exchanges as a dual-listed company.

In the 2020 Forbes Global 2000, BHP Group was ranked as the 93rd-largest public company in the world. In January 2022, BHP relinquished its London Stock Exchange listing, becoming a solely Australian Securities Exchange listed company. As of 2022, BHP is the largest company in Australia, and the largest mining company in the world, by market capitalization.

BHP has mining operations in Australia, North America, and South America, and petroleum operations in the U.S., Australia, Trinidad and Tobago, the UK, and Algeria. The company has four primary operational units: Coal, copper, iron ore, and petroleum.

Until January 2022, BHP was a dual-listed company; the Australian BHP Billiton Limited and the British BHP Billiton plc were separately listed with separate shareholder bodies while conducting business as one operation with identical boards of directors and a single management structure. The headquarters of BHP Billiton Limited and the global headquarters of the combined group was located in Melbourne, Australia. The headquarters of BHP Billiton plc are located in London, England. Its main office locations are in Australia, the U.S., Canada, the UK, Chile, Malaysia, and Singapore.
