Jaime Milans del Bosch y Ussía (8 June 1915 – 26 July 1997) was a lieutenant general in the Spanish Army who was dismissed and imprisoned in 1981 for his role in the failed coup d'état of 23 February 1981.

After the war, he held successive positions as military attaché in Spanish embassies in Latin American countries, including Argentina, Uruguay, Chile and Paraguay.

In 1981, Milans del Bosch was the only senior army commander who supported the coup d'état attempt without reservation and conducted offensive operations of importance.

On 23 February 1981, shortly after Antonio Tejero had stormed the Spanish Congress of Deputies, he ordered tanks onto the streets of Valencia and decreed a state of emergency.

After the televised message of King Juan Carlos I, those in the military who had not yet committed themselves decided to remain on the side of the government, causing the coup to fail.
