James Douglas, Earl of Angus (1671 – 3 August 1692) was a Scottish nobleman and soldier.
He was born at Douglas Castle, Douglas, South Lanarkshire. The son of James Douglas, 2nd Marquess of Douglas and his first wife Lady Barbara Erskine, eldest daughter of John Erskine, 20th Earl of Mar.
Angus was sent for his education to a private residence, in England, to be tutored by a Master Abernethy. His father's impecunious position aroused the interest of King Charles II who wrote to the Lord Chancellor of Scotland, George Gordon, 1st Earl of Aberdeen :
Being informed that Lord Angus is in a private place within some miles of London, and haveing a more than ordinary concern in his education, both on the account of his immediat descent from the most loyall and ancient family of Douglas (by which so many signall services have been performed to our royal predecessors for many ages), and of the earnest desire we have that, in case of his liveing to represent it, he may not in his younger years becorrupted with ill principles, we have thought fit hereby to authorise you to speak with his father the Marques of Douglas, and to know from him to whose carehe has committed a trust of so much importance to our service and to himself, as is that of his son's education, at such a great distance from his relations, to the end that if, upon notice thereof from you, we shall not have reason to be therewith well satisisfied we may order a better course to be taken in reference to his breeding. It is our will and pleasure that you call for from the Marques, and transmit to usan account of the present condition of his eatate, particularly of the burden of debts wherewith it stands affected, and of the true extent of the yearly rent, both reall and casuall; as also of the courses (if any be) set down for the discharge of these debts, wherein you are to take the assistance of some of the nearest relations of the family. For truly we have so great a regard, not only to the standing thereof, but also its continuance in a splendid and plentiful condition, as we cannot but highly concern ourselfe in the right management of their fortune
