Sir Robert Munro, 5th Baronet of Foulis (died 11 September 1729) was also 23rd Baron and 26th chief of the Clan Munro. He became blind and was known as the Blind Baron.
Robert Munro was the eldest son of Sir John Munro, 4th Baronet of Foulis. Robert was granted a charter by King William III of Great Britain for confirmation of the lands and barony of Foulis, as well as all of his other estates. Robert represented the County of Ross in Parliament from 1697 to 1702. Sir Robert along with many other Munros is amongst the people of Sutherland and Ross who signed an address to King George I of Great Britain, in December 1714, imploring his Royal mercy for Simon Fraser, Lord Lovat, chief of Clan Fraser, on his return from France at the instigation of Major James Fraser of Castleleathers.
In 1715 William Mackenzie, 5th Earl of Seaforth led a force of 3000 men headed by the Clan Mackenzie which also included men from the Clan MacDonald, Clan MacKinnon, Clan MacRae and the Clan Chisholm. He was opposed by Robert's eldest son and heir, Colonel Sir Robert Munro of Foulis who had formed a camp at the Bridge of Alness with 600 men which also included men from the Clan Ross. Munro had sent many of his own men south to protect the lands of the Clan Forbes of Culloden from the Jacobites. Munro was soon joined by the Earl of Sutherland and the Chief of Clan Mackay who both brought with them only a portion of their clans and expected support from the Clan Grant did not arrive. The Earl of Seaforth's forces advanced on the Sutherland's camp who made a quick retreat to avoid contact with their more powerful foe. Soon afterwards a council of war was held between the two sides and the Sutherlanders and Mackays peacefully moved back north to their own territory, while much of the Ross's lands were ravaged and the Munros returned home to find their lands of Ferindonald and Foulis Castle had been plundered.
