PY Ta 641, sometimes known as the Tripod Tablet, is a Mycenaean clay tablet inscribed in Linear B, currently displayed in the National Archaeological Museum, Athens. Discovered in the so-called "Archives Complex" of the Palace of Nestor at Pylos in Messenia in June 1952 by the American archaeologist Carl Blegen, it has been described as "probably the most famous tablet of Linear B". The tablet catalogues tripods and other vessels used in ritual feasting.
