The Liverpool Rifles was a unit of the Territorial Army, part of the British Army, formed in Lancashire as a 'Rifle Volunteer Corps' (RVC) in 1859, becoming a battalion of the King's Regiment (Liverpool) in 1881. It saw action on the Western Front in the First World War and later became a searchlight unit of the Royal Artillery in the Second World War.

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).
