The Royal Regiment of Fusiliers (RRF) is an infantry regiment of the British Army, part of the Queen's Division.

The regiment was formed on April 23, 1968, as part of the reforms of the army that saw the creation of the first 'large infantry regiments', by the amalgamation of the four English fusilier regiments.

On 23 April 1968 the Royal Regiment of Fusiliers was formed from the four English fusilier regiments. Each of these regiments were steeped in history and traditions which have been retained by the regiment today.

On formation, the regiment consisted of four Regular battalions, one Volunteer battalion covering the four Regimental areas and the Depot. Due to a series of Government Defence Reviews, 'Options for Change' and the recent 'Strategic Defence Review' the regiment now comprises two Regular battalions and a number of Territorial Army companies located in the four Regimental Areas.

The Regular battalions are:

As one of the existing large infantry regiments, the Royal Regiment of Fusiliers is unaffected by the reforms of the infantry that were announced in December 2004 although the regiment received a TA battalion, the 5th Battalion RRF, through the redesignation of Tyne-Tees Regiment, on 1 April 2006. The TA battalion will however retain a multi-badged identity, with C (Durham Light Infantry) Company remaining one of the three rifle companies.
