The Queen's Own Royal West Kent Regiment was a line infantry regiment of the British Army based in the county of Kent in existence from 1881 to 1961. The regiment was created on 1 July 1881 as part of the Childers Reforms, originally as the Queen's Own (Royal West Kent Regiment), by the amalgamation of the 50th (Queen's Own) Regiment of Foot and the 97th (The Earl of Ulster's) Regiment of Foot. In January 1921, the regiment was renamed the Royal West Kent Regiment (Queen's Own) and, in April of the same year, was again renamed, this time as the Queen's Own Royal West Kent Regiment.

After distinguished service in the Second Boer War, along with both the First and the Second World Wars, on 1 March 1961, the regiment was amalgamated with the Buffs (Royal East Kent Regiment) to form the Queen's Own Buffs, The Royal Kent Regiment, which was destined to be short-lived. On 31 December 1966, the Queen's Own Buffs was merged with the other regiments of the Home Counties Brigade—the Queen's Royal Surrey Regiment, the Royal Sussex Regiment and the Middlesex Regiment—to form the Queen's Regiment, which was in turn amalgamated with the Royal Hampshire Regiment, on 9 September 1992, to form the Princess of Wales's Royal Regiment (Queen's and Royal Hampshires). Throughout its existence, the Queen's Own Royal West Kent Regiment was popularly and operationally known as the Royal West Kents.

When the regiment was formed, Kent was one of five counties (the others being Surrey, Staffordshire, Lancashire and Yorkshire) that was split to create more than one regiment. Kent was split into two areas, with those in West Kent forming the Queen's Own Royal West Kent Regiment, while those in East Kent becoming the Buffs (East Kent Regiment). The dividing line that separated the two regimental areas was east of the River Medway. The regiment's recruitment area covered both the towns and rural areas of West Kent and a number of south-east London suburbs that were later included in the County of London.

The Childers reforms also affiliated Militia and Volunteer battalions with their local county regiments, giving the Royal West Kents the following organisation:

Regulars

Militia

Volunteers

The 1st Battalion fought at the second battle at Kassassin on 9 September 1882 and at the Battle of Tel el-Kebir a few days later during Anglo-Egyptian War. It then spent two years on garrison duty in Cyprus before being transferred to Sudan, where it fought at the Battle of Ginnis during the Mahdist War. It spent the years up to the outbreak of the First World War on garrison duty, including at Ceylon (together with the 2nd battalion) and Malta.
