The Ninth Dynasty of ancient Egypt (sometimes notated Dynasty IX) is often combined with 7th, 8th, 10th and early 11th Dynasties under the group title First Intermediate Period.

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".
Rulers
The 9th Dynasty was founded at Herakleopolis Magna, and the 10th Dynasty 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 differing opinions about the order of succession within the two dynasties. Among them, only Meryibre Khety and Nebkaure Khety are undoubtedly attested by archaeological finds:
