The Westmorland and Cumberland Yeomanry was a Yeomanry Cavalry Regiment of the British Army that was formed in 1819. The regiment provided troops for the Imperial Yeomanry during the Second Boer War and served on the Western Front in the First World War, latterly as infantry. The regiment converted to artillery in 1920 and served as such in the early years of the Second World War, before becoming part of the Chindits in Burma. Post war it served as a gunner regiment until 1971 when the title disappeared.
