John Stephen Hampton (c. 1806 – 1 December 1869) was Governor of Western Australia from 1862 to 1868.
Little is known of John Hampton's early life. His death certificate states that he was born in 1810, but other evidence suggests 1806 or perhaps 1807; these latter figures are considered more likely. He undertook medical studies at Edinburgh, graduating with a diploma of medicine in September 1828. He was appointed an assistant naval surgeon with the Britannia, but shortly afterwards was transferred to the Sphinx. In 1832 he was attached to the Plymouth dockyards, where he worked to prevent the spread of cholera. He later served on the Savage, the Firebrand and finally the Portland. In December 1834 he was promoted to full surgeon, and in March 1843 became surgeon-superintendent. Between 1841 and 1845, Hampton was surgeon-superintendent on a series of convict ships to Van Diemen's Land: the Mexborough, the Constant and the Sir George Seymour.
Having served well on a number of convict ships to Van Diemen's Land, Hampton was appointed Comptroller-General of Convicts in Van Diemen's Land in May 1846. He arrived at the colony on 27 October 1846. During his time in the office, allegations of inhumanity and corruption were frequently published in the press. In 1855, the Tasmanian Legislative Council established a select committee to look into the allegations. Hampton was summonsed to appear in the House for questioning, but refused. The House then found him guilty of contempt and issued a warrant for his arrest, but both the police magistrate and the local sheriff refused to help arrest him. Hampton eventually wrote a letter to the Council, in which he agreed to remain under house arrest until the legality of the warrant had been established. The Council refused to accept this proposal, but a political crisis was averted when the Governor of Tasmania Fox Young appointed a judicial tribunal to pronounce on the legality of the warrant, then prorogued parliament.
