The AMX-30E (E stands for España, Spanish for Spain) is a Spanish main battle tank based on France's AMX-30. Although originally the Spanish government sought to procure the German Leopard 1, the AMX-30 was ultimately awarded the contract due to its lower price and the ability to manufacture it in Spain. 280 units were manufactured by Santa Bárbara Sistemas for the Spanish Army, between 1974 and 1983.

The AMX-30 is a main battle tank designed by Ateliers de construction d'Issy-les-Moulineaux and first delivered to the French Army in August 1966. The first five tanks were issued to the 501st Régiment de Chars de Combat in August of that year. The production version of the AMX-30B weighed 36 metric tons, and sacrificed protection for increased mobility. The French believed that it would have required too much armour to protect against the latest anti-tank threats, thereby reducing the tank's maneuverability. Protection, instead, was provided by the speed and the compact dimensions of the vehicle, including a height of 2.28 metres. It had a 105 mm gun, firing a then advanced high-explosive anti-tank (HEAT) warhead known as the Obus G. The Obus G used an outer shell, separated from the main charge by ball bearings, to allow the round to be spin stabilized by the gun without spinning the warhead inside which would disrupt jet formation. Mobility was provided by the 720 horsepower (540 kW) HS-110 diesel engine, although the troublesome transmission adversely affected the tank's performance.
