Earl of Strathmore and Kinghorne is a title in thePeerage of Scotland and thePeerage of the United Kingdom. The earl is alsoChief ofClan Lyon.

The established history ofClan Lyon states that the family is of French origin, with the original namede Leonne, butJames Balfour Paul, in hisScots Peerage, states that the family is likely ofCeltic origin. The family's earliest recorded possessions, thethanages of Glamis, Glamis, Tannadyce and Belhelvies, were in a Celtic stronghold, while government positions held by family chiefs would have required fluency inGaelic.^[1]

The first recorded family member,John Lyon, Lord of Glamis, was a courtier and diplomat, who was appointedKeeper of the Privy Seal in 1371 on the accession ofRobert II. He acquired significant lands, and on 18 March 1372, Robert II granted him "the free barony of Glamuyss in the sheriffdom of Forfar." Glamis has remained the seat of the family ever since.^[1] His descendantPatrick Lyon, 1st Lord Glamis was created the firstLord Glamis in thePeerage of Scotland in 1445.

In 1606, the earldom was first created asEarl of Kinghorne in the Peerage of Scotland for Patrick Lyon, the ninth Lord Glamis, who was also createdLord Lyon and Glamis at the same time. In 1677, the designation of the earldom was changed to "Strathmore and Kinghorne" for Patrick Lyon, the third Earl. He was also granted the subsidiary titles ofViscount Lyon andLord of Glamis, Tannadyce, Sidlaw and Strathdichtie. The 10th Earl sat in theHouse of Lords as aScottish representative peer from 1796 to 1806, and again from 1807 to 1812. In 1815, he was createdBaron Bowes in thePeerage of the United Kingdom, but upon his death five years later without legitimate issue, the peerage became extinct. The Scottish peerages were inherited by his younger brother, the 11th Earl.

The 11th Earl was succeeded by his grandson, the 12th Earl, who also sat in the House of Lords as a representative peer from 1852 to 1865. He married but left no children, and the peerages were inherited by his brother, the 13th Earl, who sat in the Lords as a representative peer from 1870 until 1892. In 1887, he was createdBaron Bowes ofStreatlam Castle, in theCounty of Durham, and ofLunedale, in theCounty of York, in the Peerage of the United Kingdom. This gave him and his successors an automatic seat in the House of Lords, which the earldom did not entitle them to until thePeerage Act 1963 extended that right to all holders of Scottish peerages. The 13th Earl was succeeded by his son, the 14th Earl, who in 1937 was createdEarl of Strathmore and Kinghorne in the Peerage of the United Kingdom, leading to his becoming the14th and 1st Earl of Strathmore and Kinghorne.

The eldest son of the earl usesLord Glamis as acourtesy title. Normally, the highest subsidiary title (in this caseViscount Lyon) would be used, but Lord Glamis is used instead to prevent confusion with theofficer of arms,Lord Lyon King of Arms.^[2]Queen Elizabeth The Queen Mother (1900–2002) was the daughter of the14th Earl of Strathmore and Kinghorne, and the sister ofthe 15th Earl.

The family seat isGlamis Castle, inAngus, Scotland. Other family seats wereGibside, nearBurnopfield,County Durham andStreatlam Castle, nearBarnard Castle inCounty Durham. The traditional burial place of the Earls of Strathmore and Kinghorne is in an aisle ofGlamisparish church.^[3]
