The Ramesses IX Tomb-plan Ostracon is an Ancient Egyptian ostracon made of pale limestone. It is inscribed with a layout of the tomb of the Pharaoh Ramesses IX in the KV6–Valley of the Kings, and dates from the 20th Dynasty (c. 1100 BC). The ostracon is inscribed on a sherd of approximate dimensions: 0.66m L (2/3 meter) by 0.2m W, and was found within his KV6 tomb. The surviving design layout is about 90 percent complete due to loss of micro-chip edges, especially at the break points, and a few larger flakes.
