Sir George Shenton (4 March 1842 – 29 June 1909) was a prominent businessman in colonial Western Australia, the first Mayor of Perth, and a Member of the Western Australian Legislative Council for over thirty years.
George Shenton was born in Perth, Western Australia on 4 March 1842, the eldest son of George Shenton Sr, a wealthy businessman who was Perth's first pharmacist. George Shenton Jnr was educated locally until 1855, when at the age of 13 he was sent to England to complete his education at the Wesleyan Collegiate Institute (Queen's College) in Taunton. In 1858 he returned to Perth, where he received experience working in a range of his father's businesses, including running his father's store in Geraldton, and managing the family's farm on the Greenough River
On 4 November 1868, Shenton married Julia Theresa Eichbaum in a ceremony at Fremantle.
On 5 March 1867, George Shenton Snr drowned when his schooner, The Lass of Geraldton, capsized off Mandurah in a storm. George Shenton Jnr then took over his father's businesses. The Shenton family's businesses continued to prosper over the next thirty years, but as George Shenton became more involved in politics he had less time to invest in his business activities. From 1884, his youngest brother Ernest gradually took over the running of the Perth store, and another brother, Edward, took the Geraldon business as his inheritance. This left George with responsibility for the shipping business that his father had established.
