Agios Vasileios (also spelled Ayios Vasileios or Ayios Vasilios; Greek: Άγιος Βασίλειος) is the site of a Mycenaean palace, located near the village of Xerokambi in Laconia, Greece.

It was discovered after a Linear B tablet was found accidentally on the slope of a hill, near the Byzantine chapel of Agios Vasileios (St.

Basil), in 2008; two more tablet fragments were found in a survey conducted the same year.

[1] Excavations, carried out by the Archaeological Society of Athens and directed by archaeologist Adamantia Vasilogamvrou, began in 2009 and have brought to light a palace complex with a large central courtyard with colonnaded porticos along the sides.

Finds include an archive of Linear B tablets, kept in a room adjacent to the colonnade; cult objects such as figurines made of clay and ivory; a collection of twenty bronze swords; and fragments of wall frescoes.
