Thomas Dunlop Galbraith, 1st Baron Strathclyde, PC (20 March 1891 – 12 July 1985), was a Scottish Unionist Party politician.

He was elevated to the peerage in 1955 as Lord Strathclyde (of Barskimming in the County of Ayr), and died three decades later.

[1] Galbraith's political career began in local government where he served as a councillor on Glasgow Corporation from 1933 until 1940.

Their second son was killed during the Second World War in the English Channel while captaining the French submarine chaser Chasseur 6 that was hit by a German torpedo boat.

A month later, Strathclyde died at his estate at Barskimming, in Mauchline, Ayrshire, in 1985, and the barony passed to his grandson.
