Apostolos Santas (; 22 February 1922 – 30 April 2011), commonly known as Lakis, was a Greek veteran of the Resistance against the Axis Occupation of Greece during World War II, most notable for his participation, along with Manolis Glezos, in the taking down of the German flag from the Acropolis on 30 May 1941. In 1942, he joined the fledgling National Liberation Front (EAM), and a year later the guerrilla force ELAS, with which he participated in several battles with the Axis troops throughout Central Greece.
