The Dorset Regiment was a line infantry regiment of the British Army in existence from 1881 to 1958, being the county regiment of Dorset. Until 1951, it was formally called the Dorsetshire Regiment, although usually known as "The Dorsets". In 1958, after service in the Second Boer War along with World War I and World War II, the Dorset Regiment was amalgamated with the Devonshire Regiment to form the Devonshire and Dorset Regiment. In 2007, it was amalgamated with the Royal Gloucestershire, Berkshire and Wiltshire Regiment, The Light Infantry and the Royal Green Jackets to form a new large regiment, The Rifles.
