Anastasios Balkos (Greek: Αναστάσιος Μπάλκος, 1916 – 30 October 1995) was a Greek Army lieutenant general and conservative politician, who served as Greece's Minister of Public Order and as an intelligence officer in the Greek secret services.
In the postwar years, under the conservative governments of Marshal Alexander Papagos and Constantine Karamanlis (1952–63), Balkos served in the Counterespionage and Security Branch of the Greek Central Intelligence Service (KYP), which at the time had a bad reputation, due to its repression of the Greek Left in the virulently anti-communist climate following the Civil War.
After the restoration of democracy in 1974, Balkos established friendly relations with Karamanlis and with Defense Minister Evangelos Averoff, who had much influence among the Greek "hard Right". In January 1975, Balkos was appointed General Secretary of the Ministry of Public Order.
In October 1981, he attacked the newly elected socialist Prime Minister Andreas Papandreou, because he appointed Yannis Skoularikis as Minister of Public Order; Skoularikis was a member of the communist-sponsored National Liberation Front (EAM) during the Nazi occupation and Balkos feared he would purge the security forces from conservatives in order to settle old scores.
