John Hancock (originally named John Langley Hayward; born 2 January 1976) is an Australian entrepreneur, the son of Gina Rinehart and grandson of the mining tycoon Lang Hancock.

Early life

John Hancock was born to Greg Milton, who hailed from England, and Australian Gina Rinehart. Initially named John Langley Hayward, he has a sister, Bianca Rinehart, as well as half-sisters Ginia Rinehart and Hope Welker. After family disagreements, he adopted the surname Hancock in honor of his grandfather. His education includes attendance at Phillips Academy located in Andover, Massachusetts.

Hope Margaret Hancock Trust

In 2010, together with Bianca Rinehart and half-sister Hope Welker, Hancock initiated legal proceedings against their mother concerning the administration of a family trust created by their late grandfather. Reflecting on the complexities of wealth management, Hancock stated:

"Well it'd be nice if I was, but I have all the bad things about having money and none of the good things."

Despite these disputes, he emphasizes maintaining a strong bond with his mother, mentioning that they concur on 90 percent of matters, with the remaining 10 percent being sources of tension.

The Supreme Court of New South Wales appointed Bianca Rinehart as trustee of the Hope Margaret Hancock Trust after their mother consented to step down and sought recommendations for her successor.

Hancock made his initial appearance on the Financial Review Rich List in 2020, with an estimated net worth of 2.05 billion Australian dollars. He first featured on the Forbes Australia's 50 richest individuals in 2017, sharing a combined net worth of 5.00 billion US dollars with his sister Bianca and half-sisters Ginia and Hope Welker.
