The King's Own (3rd Staffordshire) Rifle Militia, later the 4th Battalion, North Staffordshire Regiment was an auxiliary regiment raised in Staffordshire in the West Midlands of England in 1853. Under the Cardwell and Childers Reforms it became part of the North Staffordshire Regiment and saw active service during the Second Boer War. During World War I it trained reinforcements for the battalions serving overseas before proceeding to the Western Front itself and seeing a considerable amount of combat during the last year of the war. After a shadowy postwar existence it was formally disbanded in 1953.
