Thomas Fleming, 10th Baron Slane

Thomas Fleming (died 1601) was a member of the Parliament of Ireland of 1585. He was the son of James Fleming, a grandson of James Fleming, 7th Baron Slane. His mother was Ismay Dillon, daughter of Sir Bartholomew Dillon, Lord Chief Justice of Ireland.

He succeeded to the barony after the death of his cousin James Fleming, 9th Baron Slane. He was the only noble to serve with Walter Devereux, 1st Earl of Essex against Turlough Luineach O'Neill, the ruler of Ulster, in March 1574. He was one of the leaders of the opposition to the policies of Sir John Perrot, the Lord Lieutenant of Ireland, in the 1580s.

He married Catherine Preston, daughter of Jenico Preston, 3rd Viscount Gormanston. They had no sons, but later Barons were descended from their daughter Eleanor, who married her cousin William, 11th Baron Slane.
