The Ninth Dynasty of ancient Egypt (notated Dynasty IX) is often combined with Dynasties VII, VIII, X and XI (Thebes only) under the group title First Intermediate Period. Dynasties IX and X date approximately from 2160 to 2025 BC. The dynasty that seems to have supplanted the 8th Dynasty is extremely obscure. The takeover by the rulers of Herakleopolis was violent and is reflected in Manetho's description of Achthoes, the founder of the dynasty, as 'more terrible than his predecessors', who 'wrought evil things for those in all Egypt".
Dynasty IX was founded at Herakleopolis Magna, and Dynasty X continued there. At this time Egypt was not unified, and there is some overlap between these and other local dynasties. The Turin Canon lists eighteen kings for this royal line, but their names are damaged, unidentifiable, or lost.
The following is a possible list of rulers of the Ninth Dynasty based on the Turin Canon, as egyptologists have not unanimous opinions about the order of succession within the two dynasties. Among them, only Meryibre Khety and Nebkaure Khety are undoubtedly attested by archaeological finds:
