Thomas Brisbane, Scottish general and politician, 6th Governor of New South Wales (d. 1860)
Major General Sir Thomas Makdougall Brisbane, 1st Baronet, (23 July 1773 – 27 January 1860), was a British Army officer, administrator, and astronomer. Upon the recommendation of the Duke of Wellington, with whom he had served, he was appointed governor of New South Wales from 1821 to 1825.

A keen astronomer, he built the colony's second observatory and encouraged scientific and agricultural training. Rivals besmirched his reputation and the British Secretary of State for the Colonies, Lord Bathurst, recalled Brisbane and his colonial secretary Frederick Goulburn. Brisbane, a new convict settlement, was named in his honour and is now among the largest cities in Australia.
