The Liverpool Scottish, known diminutively as "the Scottish", is a unit of the British Territorial Army, raised in 1900 as an infantry battalion of the King's (Liverpool Regiment). Following reconstitution into the Territorial Army in 1920, the Liverpool Scottish formalised its relationship with the Queen's Own Cameron Highlanders and transferred in 1937 to become the regiment's second territorial battalion.
