Meryibre Khety, also known by his Horus name Meryibtawy, was a pharaoh of the 9th or 10th Dynasty of Egypt, during the First Intermediate Period.

It seems that Meryibre ruled over his neighboring nomarchs with an iron fist, and it is likely for this reason that in later times this ruler became Manetho's infamous Achthoes,[3] a wicked king who went insane and then was killed by a crocodile.

Alternatively, other Egyptologists such as Jürgen von Beckerath[5] believe instead that Meryibre reigned toward the end of the subsequent 10th Dynasty, shortly before king Merikare.

A sort of copper brazier or basket from a tomb near Abydos (found along with a scribe's palette bearing the name of king Merikare) and now exhibited at the Louvre Museum, an ebony wand from Meir now at the Cairo Museum (JE 42835), an ivory casket fragment from Lisht and some other minor finds.

[2][3] Thanks to those few monuments, however, Meryibre's royal titulary is the most complete amongst the known pharaohs of this period.
