The Royal Canadian Regiment (The RCR) is an infantry regiment of the Canadian Army. The regiment consists of four battalions, three in the Regular Force and one in the primary reserve. The RCR is ranked 1st in the order of precedence amongst Canadian Army infantry regiments, but in a quirk of the rules of seniority, its 4th battalion is 9th.

The RCR was originally authorized as the Infantry School Corps on 21 December 1883, and established its first three company stations at Fredericton, New Brunswick; St Jean, Quebec; and Toronto, Ontario. In 1887 a fourth company was authorized and the next year was established at London, Ontario. Now consisting of three Regular Force battalions and one Reserve Force battalion, the regiment's four battalions are now stationed in Ontario and New Brunswick. With many of its soldiers drawn from Ontario and the Atlantic Provinces in recent decades, the regiment maintains a general connection as the "local" infantry regiment for anglophone eastern Canada.

The RCR maintains a Regimental Headquarters (RHQ) in Petawawa, Ontario, which has no operational command role but handles regimental affairs outside the responsibility of the individual battalions. The Royal Canadian Regiment Museum is located within historic Wolseley Hall in London, Ontario. Wolseley Barracks in London has been continuously occupied by some element of the regiment since construction of Wolseley Hall was completed in 1888. At various times Wolseley Barracks has been the home of the Regimental Headquarters, the 1st and 2nd Battalions, and remains the home of the 4th Battalion today.

The Royal Canadian Dragoons (RCD) is the senior armoured regiment of the Canadian Army by precedence. It is one of three armoured regiments in the Regular Force and forms part of the Royal Canadian Armoured Corps.

The colonel-in-chief of The RCD is Charles, Prince of Wales. The colonel of the regiment is Brigadier-General Peter Atkinson (Retired).

The commanding officer is Lieutenant-Colonel E.A. Kerckhoff, and the regimental sergeant major is Chief Warrant Officer S. Larouche.

The regiment is composed of Regimental Headquarters, "A", "B", "C", "D" and Headquarters Squadrons. "A", "B" and "D" Squadrons, based at CFB Petawawa, are light armoured cavalry squadrons. "C" Squadron, based at CFB Gagetown, is equipped with 21 Leopard 2 tanks (models A4, A4M and A6M) and the squadron consists of both Dragoons and members of 12e Régiment blindé du Canada. Headquarters Squadron, based in Petawawa, provides first-line combat service support to the regiment.
