Alexandros Tziolis (Greek: Αλέξανδρος Τζιώλης) (born February 13, 1985 in Katerini) is a Greek footballer.

Alexandros began his playing career as a teenager in a local team called Apollon Litochorou. He played there for about 7 years and in 2002, a Panionios scouter spotted his talent and brought him to Athens. He was an integral part of Panionios team for about 4 seasons, playing 61 matches and scoring 3 goals. As a result, Panathinaikos FC offered Panionios 650.000€ and signed him. Hardy, tall and strong, Tziolis is considered a promising defensive midfielder and is often mentioned as a potential successor to Theodoros Zagorakis in the Greece national team.
