The Hamersley family were a wealthy and well-connected family of early settlers in the colony of Western Australia. Members of the Hamersley family emigrated to Western Australia from England in 1837. Prominent members and connections of the family include:
- Edward Hamersley, pastoralist and MLC;
- his sister Frances, who married William Locke Brockman;
- their son Edmund Ralph Brockman;
- their son Henry Brockman;
- his son Edward, pastoralist and MLC;
- his wife Jane, sister of Andrew and Charles Dempster;
- his son Samuel, pastoralist, explorer, MLA and MLC;
- his wife Matilda, sister of Maitland Brown;
- his son Vernon, MLC;
- his daughter Margaret, who married Sir John Forrest;
- his daughter Flora, who married Frederick North;
- their son Charles North;
- his nephew Malcolm, who accompanied John Forrest on his 1869 exploring expedition.
- his sister Frances, who married William Locke Brockman;
A number of places in Western Australia have been named after the Hamersley family. John Septimus Roe named the Hamersley River in their honour in 1848–49; and Francis Gregory also named the Hamersley Range in the Pilbara region in their honour. John Forrest, during his 1869 exploring expedition, named Mount Malcolm, Mount Flora and Mount Margaret all in honour of members of the Hamersley family. The Hamersley ward of the City of Stirling (formerly Perth Road Board), the suburb of Hamersley, settled in the late 1960s, and a golf course in North Beach are all named after them. Their 19th-century home, Hamersley House in Beachton Street, North Beach, was demolished in 1962.
