詹姆士·斯圖亞特（James Denham Steuart,1712～1780）是英國的經濟學家，重商主義後期代表人物。1767年著作了《政治經濟學原理研究》，
Sir James Denham-Steuart, 7th Baronet (21 October 1712 – 26 November 1780) was a British economist.
He was the only son of Sir James Steuart, Solicitor General for Scotland under Queen Anne and George I, and was born at Edinburgh. After passing through the University of Edinburgh he was admitted to the Scottish bar at the age of twenty-four.
He then spent some years on the Continent, and while in Rome entered into relations with the Young Pretender, Charles Edward Stuart. He was in Edinburgh in 1745, and so compromised himself that, after the battle of Culloden, he found it necessary to return to the Continent, where he remained until 1763. It was not indeed until 1771 he was fully pardoned for any complicity he may have had in the rebellion. He died at his family seat, Coltness, in Lanarkshire.
In 1767 was published Steuart's Inquiry into the Principles of Political Economy. It was the most complete and systematic survey of the science from the point of view of moderate mercantilism which had appeared in England. But the time for the mercantile doctrines was past. Nine years later the Wealth of Nations was given to the world. Adam Smith never quotes or mentions Steuart's book; being acquainted with Steuart, whose conversation he said was better than his book, he probably wished to keep clear of controversy with him.
The German economists examined Steuart's treatise, especially in relation to the theory of value and the subject of population. They pointed out that he dwelt on the special characters which distinguish the economies proper to different nations and different grades in social progress. Hegel read it at a formative time.
