Hyksos is a term which, in modern Egyptology, designates the kings of the Fifteenth Dynasty of Egypt. The seat of power of these kings was the city of Avaris in the Nile Delta, from where they ruled over Lower Egypt and Middle Egypt up to Cusae.

The Fifteenth Dynasty was a foreign dynasty of ancient Egypt. It was founded by Salitis, a Hyksos from West Asia whose people had invaded the country and conquered Lower Egypt. The 15th, 16th, and 17th Dynasties of ancient Egypt are often combined under the group title, Second Intermediate Period. The 15th Dynasty dates approximately from 1650 to 1550 BC.
