General John Campbell, 4th Duke of Argyll, KT, PC (c. 1693 – 9 November 1770) was a Scottish military officer, Whig politician and peer who sat in the British House of Commons from 1713 to 1761.

[1] He acquired Coombe Bank, at Sundridge, near Sevenoaks Kent, where he commissioned Roger Morris to build a country house for him in the second quarter of the 18th century.

However, he soon entered the world of politics, and at the 1713 general election, he was returned unopposed as Member of Parliament (MP) for the alternating seat of Buteshire.

[6] He was returned unopposed again for Dumbartonshire at the 1754 general election, and supported Newcastle's administration and voted in its defence in the division on Minorca in 1757.

He was returned again at the 1761 general election, but succeeded to the Dukedom two days later and had to vacate his seat in the House of Commons.

Upon inheriting the dukedom and other titles upon the death of his cousin Archibald Campbell, 3rd Duke of Argyll in 1761,[8] he left the House of Commons and became Governor of Limerick and a Scottish representative peer.
