Thomas Scott (baptised 18 October 1746 – July 29, 1824) was a judge and political figure in Upper Canada.

He was born in the parish of Kingoldrum, Angus, Scotland and studied law at Lincoln's Inn in London. He was called to the bar in 1793. In 1800, he was appointed attorney general in Upper Canada and arrived in York in 1801. He was appointed to the Executive Council for the province in 1805. He was the fourth Treasurer of the Law Society of Upper Canada from 1805 until he became Chief Justice for Upper Canada succeeding Henry Allcock and was appointed to the Executive Council in 1806.^[1]

In 1811, already suffering from ill health, Scott applied for a pension so that he could retire, but was refused. During the War of 1812, the administration sought to ensure the loyalty of its subjects by imposing martial law and, in 1814, by prosecuting those who had expressed sympathy for the enemy with treason in a series of trials at Ancaster known as the "Bloody Assize". Fifteen men were condemned to death of which eight were executed. These actions increased Scott's workload.

In 1816, Scott was finally granted a pension and retired. He was succeeded by William Dummer Powell as Chief Justice for the province. Scott died at York (Toronto) in 1824.
