The Hellenic Athletics Federation (Greek: Σύνδεσμος Ελληνικών Γυμναστικών Αθλητικών Σωματείων; abbreviated SEGAS) is Greece's governing body for amateur sport.

SEGAS was created in 1897 and has been the principal organiser of many international sporting competitions held in Greece.

SEGAS is putting together the Athens Classic Marathon taking place in November this year.

[citation needed] When two Greek sprinters were barred from the Athens Olympics in 2004 for drug abuse, SEGAS set up an independent tribunal to review the ban.

[1] They are located at 137 Syngrou Avenue, Nea Smirni, Athens.
