The 63rd Tank Regiment (Italian: 63° Reggimento Carri) is an inactive tank regiment of the Italian Army, which was based in Cordenons in Friuli-Venezia Giulia and last operationally assigned to the 132nd Armored Brigade "Ariete".

The unit's lineage traces back to the World War II LXIII Tank Battalion L, which in 1940 participated in the Italian invasion of Egypt.

On 16 September 1940, the Italian formations reached the harbor of Sidi Barrani in Egypt and went on the defensive.

On 9 December 1940, the British Western Desert Force commenced Operation Compass with an attack against the Italian positions at Sidi Barrani.

The next day, on 10 December 1940, units of the British 7th Armoured Division reached Buq Buq and the LXIII Tank Battalion L with its tankettes was overcome and heavily decimated by superior British Matilda II and Cruiser tanks.

Due to a lack of fuel the remaining L3/35 tankettes were buried in the sand as strong points.

After the surrender of the Italian garrison of Tobruk, the LXIII Tank Battalion L was declared lost due to wartime events on 25 January 1941.

Tank and armored battalions created during the 1975 army reform were named for officers, soldiers and partisans of the tank speciality, who had served in World War II and been awarded Italy's highest military honor the Gold Medal of Military Valor.

The 63rd Tank Battalion was named for Second Lieutenant Vincenzo Fioritto, who, as commanding officer of a platoon of the 4th Tank Infantry Regiment's depot, fell on 10 September 1943 during the attempt to defend Rome against invading German forces.
