The Liverpool Scottish, known as "the Scottish", was a unit of the British Army, part of the Army Reserve, raised in 1900 as an infantry battalion of the King's. The Liverpool Scottish became affiliated to the Queen's Own Cameron Highlanders in the 1920s and formally transferred to the regiment in 1937 with its identity preserved. Reflecting the Territorial Army's decline in size since the late 1940s, the battalion was reduced to a company in 1967, then to a platoon of "A" (King's) Company, King's and Cheshire Regiment in 1999. In 2006, the company was incorporated into the 4th Battalion, Duke of Lancaster's Regiment.

The King's Regiment (Liverpool) was one of the oldest line infantry regiments of the British Army, having been formed in 1685 and numbered as the 8th (The King's) Regiment of Foot in 1751. Unlike most British Army infantry regiments, which were associated with a county, the King's represented the city of Liverpool, one of only four regiments affiliated to a city in the British Army. After 273 years of continuous existence, the regiment was amalgamated with the Manchester Regiment in 1958 to form the King's Regiment (Liverpool and Manchester), which was later amalgamated with the King's Own Royal Border Regiment and the Queen's Lancashire Regiment to form the present Duke of Lancaster's Regiment (King's, Lancashire and Border).
