The Franchthi or Frankithi cave is a prehistoric site in the Greek Peloponnese. The cave shows occupation from the epipalaeolithic c, 10,000 BC and, following a hiatus, it was reoccupied in the Mesolithic between 7500 and 6000 BC.

Obsidian items from the cave have been traced to the island of Melos 80 miles away by sea, which indicates that boats were used in the period. Around 5800 BC evidence of domesticated animals appears in the archaeological record at the cave.
