The Worcestershire Regiment was a line infantry regiment of the line in the British Army, formed in 1881 under the Childers Reforms by the amalgamation of the 29th (Worcestershire) Regiment of Foot and the 36th (Herefordshire) Regiment of Foot. The regiment fought in many conflicts, including both the First and Second World War, until 1970 when it was amalgamated with the Sherwood Foresters (Nottinghamshire and Derbyshire Regiment) to form the Worcestershire and Sherwood Foresters Regiment (29th/44th Foot) which was, in September 2007, amalgamated again with the Cheshire Regiment and the Staffordshire Regiment (Prince of Wales's) to form the Mercian Regiment.

During the Second World War 994 officers and other ranks of the Worcestershire Regiment were killed in action or died of their wounds, the average age being 26. However, the regiment was awarded 36 battle honours.
