Luis Carrero Blanco, Spanish admiral and politician, 69th President of the Government of Spain (d. 1973)

Luis Carrero Blanco (4 March 1904 – 20 December 1973) was a Spanish Navy officer and politician, who served as Prime Minister from June 1973 until his assassination in December of that year. He participated in the Rif War, and later the Spanish Civil War, in which he supported the Nationalist faction.

Carrero Blanco, a long-time confidant and right-hand man of Francisco Franco, was one of the most prominent figures in the Francoist dictatorship's power structure and held throughout his career a number of high-ranking offices such as those of Undersecretary of the Presidency from 1941 to 1967 and Franco's deputy from 1967 to 1973. He also was the main drafter behind the 1947 Law of Succession to the Headship of the State. Carrero ended up succeeding the Spanish dictator, Franco, as head of government in June 1973.

Shortly after he became prime minister, Carrero Blanco was assassinated in a roadside bombing on 20 December 1973 by the Basque nationalist group Euskadi Ta Askatasuna (ETA) while he was returning from Mass in his car. He was posthumously awarded the nobiliary title of Duke of Carrero Blanco.
