The 2nd Cuirassier Regiment (French: 2e régiment de cuirassiers or 2e RC) was an armoured unit of the French Army, which originated as a cavalry and then a cuirassier regiment. It was descended from the régiment Cardinal-Duc, which is at the top of the list of twelve cavalry regiments created by the same royal ordnance of 16 May 1635 - this made the 2nd Cuirassier Regiment the oldest surviving cavalry regiment in the French Army, until its disbandment in 1991.
