Earl of Strathmore and Kinghorne is a title in the Peerage of Scotland and the Peerage of the United Kingdom. It was first created as Earl of Kinghorne in Peerage of Scotland in 1606 for Patrick Lyon. In 1677, the designation of the earldom changed to "Strathmore and Kinghorne". A second earldom was bestowed on the 14th Earl in the Peerage of the United Kingdom in 1937, leading to him being titled as the 14th and 1st Earl of Strathmore and Kinghorne.

Thomas Lyon-Bowes was the first child of Thomas Lyon-Bowes, Lord Glamis, and his wife Charlotte Lyon-Bowes née Grimstead, great-grandparents of Elizabeth Bowes-Lyon, who became queen consort in 1936. Although Thomas is recorded in Robert Douglas' Peerage of Scotland as "born and died, October 21, 1821," rumours began to circulate during the late 19th century that the child had been born deformed, and had therefore been brought up in seclusion hidden away in Glamis Castle in Angus, Scotland, giving rise to the soubriquet of the Monster of Glamis, or the Horror of Glamis.
