Lieutenant General Sir Andrew Clarke, GCMG CB CIE (27 July 1824 – 29 March 1902) was a British soldier and governor, as well as a surveyor and politician in Australia.

As a lieutenant in command of a detachment of Royal Engineers, Clarke sailed with the new lieutenant-governor, Sir William Denison, aboard the Windermere and arrived at Hobart on 26 January 1847.

His father's death the following next month left Clarke with little reason to remain in Australia but he continued to superintend convict labour and to survey the area around Hobart and design wharf accommodation and became friends with William Denison.

He and his detachment worked mainly on road building, and Clarke discovered his gift for dealing with native peoples when he was sent on a peace-making mission to the Bay of Islands.

[1] In 1849 Clarke returned to Hobart to become private secretary to William Denison, Governor of Tasmania and New South Wales, and was also an official nominee in the Tasmanian Legislative Council in 1851–53 and controller of the mounted police.

He was also responsible for the drafting and successful inauguration of the Municipal Institutions Act in December 1854, which provided for local government based on the English model in Melbourne's growing suburbs, on the goldfields, and in the country.

[1] At the 1856 elections, Clarke mounted a successful campaign against David Blair for the South Melbourne seat in the Victorian Legislative Assembly, which he held until he left the colony.

Clarke played a key role in positioning Singapore as the main port for the Malay states of Perak, Selangor and Sungei Ujong.

As Governor of the Straits Settlements, Clarke was famous for signing the Treaty of Pangkor in 1874, which established a British protectorate over the Malay States.

In that same year, Clarke successfully enforced a check on the abuse of coolies with support of the prominent Chinese leaders and European merchants.

After a number of piracy attacks took place in Selangor, Andrew Clarke assigned Frank Swettenham as a live-in advisor to Sultan Abdul Samad in August 1874.

After Clarke's retirement from the army, he unsuccessfully contested Chatham for the House of Commons of the United Kingdom in 1886 and 1892 as a follower of William Ewart Gladstone and Home Rule.
