Pentawer (also Pentawere and Pentaweret) was an ancient Egyptian prince of the 20th Dynasty, a son of Pharaoh Ramesses III and his secondary wife, Tiye.

[5] Susan Redford speculates that Pentawer, being a noble, was given the option to kill himself by taking poison and so be spared the humiliating fate of some of the other conspirators who were executed.

[4] In recent times, the Egyptologist Bob Brier has revived the old hypothesis that the famed mummy of the "Unknown Man E" found in the Deir el-Bahari cache (DB320) might, indeed, be Pentawer.

[9] The mummy is very unusual because it appears to have been embalmed quickly, without removing the brain and viscera, and to have been placed in a cedar box, the interior of which had to be crudely hacked to widen it.

Brier hypothesizes that Pentawer was mummified very rapidly and placed in an available coffin, likely by a relative, in order to give him a proper burial.
