Santameri Castle () is a castle on the mountain Skollis near the boundary of Achaea and Elis in southwestern Greece. It was one of the strongest castles, controlling the Elean fields and the mountain passes to Tritaia. It was built in 1311 by the Frankish Nicholas of Saint-Omer, who gave his name to the castle. In Venetian records it was listed as Edrolcamo (Εντρόλκαμο). Saint-Omer was lord of Thebes. Today, the walls of the castle and ruins of many buildings and a Byzantine church remain. Outside the castle is the locality Patrini where the tomb of Theodora Tocco was located.
