Air Chief Marshal Athanasios Tzoganis (Greek: Αθανάσιος Τζογάνης; born 15 July 1939) is a retired Hellenic Air Force officer who served as Chief of the Hellenic National Defence General Staff in 1996–1999.

Born in Skourtou, Aetolia-Acarnania, he entered the Hellenic Air Force Academy in 1959 and graduated first in his class in 1962.

He flew F-84, A-7, G-159, T-33, NORATLAS, C-47 and C-130 aircraft and held several staff positions and active commands (345 Bomber Squadron and 112 Fighter Wing).

According to orders, all aircraft had to depart before midnight so that darkness would provide enough cover for their return flight.

At around 24:00, Tzoganis' aircraft was ready to depart when the control tower announced the termination of all take offs.
