Thomas Dundas (c. 1708 – 30 April 1786) of Fingask and Carronhall, Stirlingshire was a Scottish merchant and politician.
In 1737, he married Anne, daughter of James Graham of Airth, a judge of the Scottish court of Admiralty.
[3][2] Dundas bought the Carronhall estate in 1749, but his career remained dependent on his increasingly powerful younger brother, in whose interest he was elected in 1768 as the Member of Parliament (MP) for Orkney and Shetland.
He held the seat until December 1770, when he was appointed as a police commissioner, and in 1771 his oldest son Thomas was returned as MP in his place.
[2] The younger Thomas went on to become a notable general in the British Army, serving briefly as Governor of Guadeloupe before his early death.
