The Carro Veloce 33 (CV 33) or L3/33 was a tankette originally built in 1933 and used by the Italian Army before and during World War II. It was based on the imported British Carden Loyd tankette. Many CV 33s were retrofitted to meet the specifications of the CV 35 in 1935. In 1938, the CV 33 was renamed the "L3/33" while the CV 35 became the "L3/35s."

A tankette is a tracked armoured fighting vehicle that resembles a small tank, roughly the size of a car. It is mainly intended for light infantry support and scouting. Colloquially it may also simply mean a small tank.
