The 8th Battalion of the Duke of Wellington's Regiment (West Riding) was a First World War battalion in the Territorial Army.
The battalion was raised in August 1914 at Halifax from new recruits. It initially formed part of the 34th Brigade (later transferring to the 32nd Brigade) of the 11th (Northern) Division in the K1 Group of Kitchener's New Army.
Following training, the battalion sailed from Liverpool in July 1915 and took part in the Gallipoli Campaign before being transferred to Egypt by January 1916. The division was redeployed to France in June 1916 to help reinforce the 3rd Army on the Western Front, and took part in battles at Flers–Courcelette, Thiepval Ridge, Messines, Langemarck, Polygon Wood, Broodseinde, and Poelcappelle.
The 8th Battalion was disbanded in February 1918.
