The Kleanthis Vikelidis Stadium or Harilaou Ground (Γήπεδο Χαριλάου) is a football stadium in Thessaloniki, Greece. It was built in 1951 as the home stadium of Aris F.C. (Thessaloniki), one of the most popular football clubs in Greece. For many years, the ground's official name was Aris Stadium, until it was renamed in honor of Kleanthis Vikelidis, a legendary player of Aris FC in the 1930s. However, most commonly referred to as "Harilaou Stadium", after the district in which it was built.
