Athinaikos, officially known as Athinaikos AS FC (Greek: Αθηναϊκός Αθλητικός Σύλλογος - Athinaikos Athlitikos Syllogos), the Athenaic Athletic Association, is a Greek football club based in the suburban town of Vyronas, located in the Athens agglomeration.

The club was formed in 1917 and was a foundation member of the Hellenic Football Federation.

At the start of the 1950s, the team was relocated to the suburbs of Vyronas and merged with Nea Elvetia (Greek: Αθλητική Ένωση Νέας Ελβετίας), the local club, which was formed in 1935.

The club was named Athinaikos Neas Elvetias AS (Greek: Αθηναϊκός Νέας Ελβετίας Αθλητικός Σύλλογος), but it was commonly referred to as Athinaikos or AthNE (Greek: ΑΘ.Ν.Ε.).

They drew the first leg 0-0 at home and took the English giants into extra-time at Old Trafford before losing 2-0.
