AEK Football Club, known simply as AEK in Greece and AEK Athens internationally, is a Greek professional football club based in Nea Filadelfeia, Attica, Greece. The team competes in the Super League Greece, the top tier of Greek football, and is one of the country's most historic clubs. This unofficial AEK Athens FC fan flag (Greek: ανεπίσημη σημαία φιλάθλων ΑΕΚ) features the club's official emblem set against a yellow-and-black vertically striped background, a design inspired by the team's iconic home jersey and traditional color identity.
The club's emblem is designed as a shield outlined in black and divided into two sections. The upper portion is white and prominently displays the initials "AEK," standing for "Αθλητική Ένωσις Κωνσταντινουπόλεως – Athlitiki Enosis Konstantinoupoleos" ("Athletic Union of Constantinople"). The larger lower section is yellow and contains the club's most recognizable symbol: a stylized black double-headed eagle. This historic Byzantine emblem represents strength, resilience, authority, and the cultural legacy of Constantinople, the ancestral homeland of the club's founders and many of its early supporters following the population exchanges of the early 20th century. The black-and-yellow color scheme is also deeply associated with Byzantine imperial symbolism and has become inseparable from the club's identity. Altogether, the crest combines historical memory, cultural heritage, and football tradition, symbolizing AEK's enduring connection to its roots and its prominent place in Greek football.
