GSO Stadium or Gymnastic Club Olympia Stadium (Greek: Γυμναστικός Σύλλογος Ολύμπια; Γ.Σ.Ο.) was a stadium in Limassol, Cyprus. In July 1892, a group of locals founded the gymnastics club "Olympia" (GSO), which is the oldest gymnastics club in Cyprus. The stadium was constructed in 1898 and opened in 1899 with the event of the 3rd Pancyprian Athletics Games. The gym then had a perimeter track about 300 meters and a capacity of 700 spectators. In 1902 horse racing competitions were held in the stadium, and in 1904 the first flower festival was organized. In 1908 the stadium held the first tennis matches. In 1910 a new 1000 spectators stand was built.
