Bay, also called Ramesse Khamenteru (died 1192 BC), was an important Asiatic official in ancient Egypt, who rose to prominence and high office under Seti II Userkheperure Setepenre and later became an influential powerbroker in the closing stages of the 19th Dynasty.

Bay's importance is emphasized by the fact that he was given permission, possibly by Seti II but more probably by Siptah, to construct his own tomb in Egypt's Valley of the Kings (KV13).

While his precise background is unknown except for his Syrian origins, Bay is first attested as scribe and butler, an important position in Egypt, during the reign of Seti II.

Bay's status at Siptah's court was so great that on several of the young king's monuments, "the chancellor is shown in scenes with the pharaoh on the same scale as the latter, the earliest occasion in which a commoner was depicted in such a manner.

Images of Bay exist showing him standing behind the throne of Pharaoh Siptah, an unusual position for a commoner, and also opposite Twosret on the doorjamb of the Amada temple where he faces the queen.

According to the information in Ostraca IFAO 1864, which is composed of two inscribed potsherd fragments that were reunited in February 2000, Bay was executed on or shortly before Year 5, III Shemu day 27 of Siptah, on the king's orders.
