The East Surrey Regiment was a line infantry regiment of the British Army in existence from 1881 until 1959. The East Surrey Regiment was formed in 1881 under the Childers Reforms from the amalgamation of the 31st (Huntingdonshire) Regiment of Foot, the 70th (Surrey) Regiment of Foot, the 1st Royal Surrey Militia and the 3rd Royal Surrey Militia.

In 1959, after service in the Second Boer War and both World War I and World War II, the East Surrey Regiment was amalgamated with the Queen's Royal Regiment (West Surrey) to form the Queen's Royal Surrey Regiment, which was, in 1966, merged with the Queen's Own Buffs, The Royal Kent Regiment, the Royal Sussex Regiment and the Middlesex Regiment (Duke of Cambridge's Own) to form the Queen's Regiment. However, the Queen's Regiment was soon amalgamated with the Royal Hampshire Regiment to form the present Princess of Wales's Royal Regiment (Queen's and Royal Hampshires).
