Seuserenre Khyan, Khian or Khayan was a king of the Hyksos Fifteenth dynasty of Egypt. His royal name Seuserenre translates as "The one whom Re has caused to be strong." Khyan bears the titles of an Egyptian king, but also the title ruler of the foreign land (heqa-khaset). The later title is the typical designation of the Hyksos rulers.
Khyan is one of the better attested kings from the Hyksos period, known from many seals and seal impressions. Remarkable are objects with his name found at Knossos and Hattusha indicating diplomatic contacts with Crete and the Hittites. A sphinx with his name was bought on the art market at Baghdad and might demonstrate diplomatic contacts to Babylon.
The remains of a palace were recently excavated at Avaris. Seal impressions of Khyan were found there, indicating that this was his palace.
