The miner started out life in 1885 as the Broken Hill Proprietary Company, or BHP, and retained that name until its 2001 merger with Anglo-Dutch mining company Billiton Plc.
Ahead of an eventual change in its official name, the company will use a new logo starting Monday, saying simply "BHP" in block letters, dropping Billiton from its name.
BHP Billiton (AU:BHP) is undergoing a rebranding that will include a major advertising campaign and the removal of the "Billiton" part its name.
BHP will run two 30-second TV commercials from tonight, release a longer version to staff and on social media and place print ads as it looks to re-position its identity around trust, respect and fostering close relationships.
"We realised we had to start by telling people what BHP Billiton is and what we do", chief external affairs officer Geoff Healy said.
"The advertisements will talk about the importance of our Australian heritage, our contribution and our commitment to communities where we operate".
The miner has largely shed the Billiton assets since.

He continued: "No, it's about. sometimes things change and you can do all the same things but sometimes it's just different". Styles squirmed at the claim and tried to deflect it with the roundabout summary: "I think it's pretty self-explanatory".
The name change harks back to the original Broken Hill Propriety Co. formed nearly 132 years ago around a silver, lead and tin mine in South Australia.
"In launching Think Big, we will take the opportunity to change our logo and move to a brand that Australians have known us by for generations - BHP", Healy said.
The re-brand comes as the company faces pressure from US hedge fund Elliott International to shift its primary stock market listing away from Australia.
Australia's treasurer, Scott Morrison, came out swinging for BHP after Elliott released its proposals publicly, warning that it was "unthinkable" that the Big Australian would be allowed to head offshore and that any attempt to move the primary listing to the United Kingdom would be blocked.
While the message of that campaign was about BHP's expansion overseas, today's rebranding was about bringing the company back to its roots, while still recognising its global operations, Mr Healy said.
Ted Horton's Big Red agency won a competitive tender for the rebranding exercise about 18 months ago.
