Chalandriani (Greek: Χαλανδριανή) is a major early Bronze Age cemetery on the island of Syros in Greece, dated to the Early Cycladic II period (Keros-Syros culture, 2600–2300 BC). The fortified prehistoric settlement of Kastri is located north of Chalandriani. Chalandriani was first excavated by Christos Tsountas in 1898.
