Penebui (died c. 3000 BC) was an early Egyptian queen and most possibly the wife of king Djer during the 1st Dynasty.

Two were found in the necropolis of king Djer at Abydos, one (pretty damaged) at Saqqara in an anonymous tomb.

The tags, called year tablets, show depictions of several ceremonies, such as a human sacrifice and the presentation of several cultic objects.

Her name is also guided by the title Weret-hetes, meaning "great one of the Hetes sceptre", identifying her as a royal spouse.

[1][2] Penebui's death seems to be recorded on the famous Palermo stone in the 4th year event window of king Djer.
