Manuel Azcárate Diz (7 October 1916 – 24 August 1998) was a Spanish journalist, politician and a leader of the Communist Party of Spain (Partido Comunista de España, PCE) in the 1960s and 1970s.

His father was Pablo de Azcárate, deputy secretary general at the League of Nations and later Spanish ambassador in London.

[1] Writing in the preface to his father's book Mi embajada en Londres durante la guerra civil española Manuel Azcárate said "In spite of the serious discussions and differences between us, he always respected the choice I had made to join the Communist party in 1934."

"[4] Azcárate married Ester Jiménez, who was depicted on a UGT poster during the civil war holding a work tool.

[7] During World War II (1939–45) Azcárate was in charge of organizing the Communist Party of Spain in the zone occupied by the Germans, and reorganized the Unified Socialist Youth (Juventudes Socialistas Unificadas).

He lived in Moscow from 1959 to 1964, where he helped write a history of the Communist Party of Spain and contributed to the book Guerra y revolución en España.

He had to deal with the awkward question of peaceful coexistence with non-communist regimes, which the Soviet Union considered to be advantageous to socialist countries by helping anti-imperialist movements while avoid the risk of war.

[1] Azcárate said in a 1977 statement to Radio Free Europe that only Eurocommunism lay outside the two blocs, a position that the French and Italian communist parties did not share.

[10] In a March 1979 interview in Encounter Azcárate said, In any case we already have a number of major US bases on our territory, and we have an agreement with the US covering military matters.

[12] In November 1981 Azcárate was among the group of PCE leaders who were expelled from the Central Committee of the party for their criticism of Carrillo's policy of sanctions.
