G.S. Iraklis Thessaloniki

Gymnastikos Syllogos Thessalonikis "Iraklis" (Greek: Γυμναστικός Σύλλογος Θεσσαλονίκης «Ηρακλής», lit. 'Thessaloniki Gymnastic Club "Heracles"'), commonly referred to as Iraklis Thessaloniki, is a multisports club based in the city of Thessaloniki, Macedonia, Greece.

G.S. Iraklis Thessalonikis was founded on 29 November 1908 and is one of the oldest and most historic sporting clubs in Greece, hence the nickname "Gireos" (Greek: Γηραιός, lit. 'Elder'). In 1910, the name "Iraklís" (Greek: Ηρακλής, lit. 'Heracles', Greek pronunciation: [iɾa'klis]) was added to the club's name to honour the ancient Greek demigod Heracles (or Hercules as the Roman equivalent), hence the nickname "Imitheos" (Greek: Ημίθεος, lit. 'Demigod'). The club's colours are blue and white, inspired by the flag of Greece.
