The Wiltshire Regiment was a line infantry regiment of the British Army, formed in 1881 under the Childers Reforms by the amalgamation of the 62nd (Wiltshire) Regiment of Foot and the 99th Duke of Edinburgh's (Lanarkshire) Regiment of Foot. The regiment was originally formed as the Duke of Edinburgh's (Wiltshire Regiment), taking the county affiliation from the 62nd Foot (which became the 1st Battalion) and the honorific from the 99th Foot (which became the 2nd Battalion). In 1921, the titles switched to become the Wiltshire Regiment (Duke of Edinburgh's).
