Gavin Campbell, 1st Marquess of Breadalbane KG PC JP DL (9 April 1851 – 19 October 1922), styled Lord Glenorchy between 1862 and 1871 and known as The Earl of Breadalbane and Holland between 1871 and 1885, was a Scottish nobleman and Liberal politician.

Campbell was born at Fermoy, County Cork, the eldest son of John Campbell, 6th Earl of Breadalbane and Holland, by Mary Theresa, daughter of John Edwards, of Dublin. He was educated at St Andrews. After his father succeeded in the earldom of Breadalbane and Holland in 1862, Campbell became known by the courtesy title Lord Glenorchy. until he succeeded his father in the earldom in 1871.

Breadalbane served as a Lieutenant in the 4th Battalion, Argyll and Sutherland Highlanders from 1873 to 1874. He was later in the Shropshire Yeomanry, from entering as Sub-Lieutenant in 1877, being promoted Lieutenant in 1882, retiring as Captain in 1887. From 1897 to 1910 he was Lieutenant-Colonel commanding the Highland Cyclist Battalion, of which he became Honorary Colonel in 1913, and was an Aide-de-Camp to King Edward VII in 1903.

As his earldom was a Scottish peerage it did not entitle him to an automatic seat in the House of Lords. However, in 1873 he was created Baron Breadalbane, of Kenmure in the County of Perth, in the Peerage of the United Kingdom, which gave him a seat in the House of Lords. Already the same year he was appointed a Lord-in-Waiting in the Liberal administration of William Ewart Gladstone. The Liberals fell from power in 1874 but returned to office in 1880, when Breadalbane was sworn of the Privy Council and appointed Treasurer of the Household by Gladstone, a post he held until 1885. The latter year he was created Earl of Ormelie, in the County of Caithness, and Marquess of Breadalbane, in the Peerage of the United Kingdom.
