Sir John Campbell, of Airds

Sir John Campbell of Ardnamurchan and of Airds, called by courtesy 7th Baronet, of Ardnamurchan and Airds (27 November 1807 - Kingstown, Saint Vincent, Saint Vincent and the Grenadines, 18 January 1853) was Lieutenant Governor of Saint Vincent and the Grenadines.

He was the only child of Lieutenant Colonel Sir John Campbell, of Airds, 6th Baronet by courtesy (15 March 1767 - 7 November 1834) and wife (m. 27 July 1803) Margaret Maxwell Campbell (c. 1776 - , Kent, 19 August 1865), sixth daughter of John Campbell, Esq., of Lochend. Sir John Campbell, of Airds Bay, gained the rank of lieutenant colonel in the service of the Argyllshire and Bute Militia. In 1804 he claimed the baronetcy of Sir Donald Campbell, 1st Baronet, of Ardnamurchan and Airds, but this claim involves a descent from an illegitimate child.

He was appointed Lieutenant Governor of Saint Vincent and the Grenadines in 1845, in which office he served until his death at Kingstown on 18 January 1853. At that time, Saint Vincent was a British dominion, having been won from the French at the Treaty of Versailles in 1783 after changing hands more than once during the mid-18th century. As Lieutenant Governor he was the highest British authority on the island, the direct representative of the Queen.

Although Sir John claimed the Baronetcy of Campbell of Ardnamurchan and Airds, his father was the first to claim it as successor to Sir Donald Campbell, the 1st Baronet. The intervening heirs (the 2nd, 3rd, 4th, and 5th Baronets) did not assume the title. Although Sir John's father, himself, and his son considered themselves rightful heirs to the baronetcy, and used the title socially, the Standing Council of the Baronetage later refused to certify their claim. Eventually the baronetcy was re-created in 1913, but again fell dormant after the death of Sir John's grandson in 1943.
