George Dempster (1732–1818) was a Scottish lawyer who was elected member of Parliament for the Perth Burghs. Dempster was educated at Dundee Grammar School (c. 1739 – c. 1748) and possibly also at the small parish school at Leuchars, Fife. On 24 February 1748 he entered the University of St Andrews and studied there until about 1750, when he left without taking a degree and moved on to study law at the University of Edinburgh. He, Andrew Erskine, and James Boswell were joint authors and a "triumvirate of wit", although he later regretted at least one of their attacks, the Critical Strictures on the New Tragedy of Elvira, as he believed the tragedy was better than anything he or his co-authors could have done. He was also one of the founding members of the Poker Club of Edinburgh.
