Alexander Forrest CMG (22 September 1849 – 20 June 1901) was an explorer and surveyor of Western Australia, and later also a member of parliament.
As a government surveyor, Forrest explored many areas of remote Western Australia, particularly the Kimberley region. Several of his expeditions were conducted alongside his brother, John Forrest, who became the first Premier of Western Australia. In later life, Forrest served in the unicameral Legislative Council from 1887 to 1890, representing the seat of Kimberley. Following the advent of responsible government, he was elected to the Legislative Assembly, representing the seat of West Kimberley from 1890 until his death. He was also mayor of Perth on two occasions, from 1892 to 1895 and from 1897 to 1900.
