The Kakuyids (also called Kakwayhids, Kakuwayhids or Kakuyah) (Persian: آل کاکویه) were a Shia Muslim dynasty of Daylamite origin that held power in western Persia, Jibal and Kurdistan (c. 1008–c.

[7][9][10] The founder of the Kakuyid dynasty was Ala al-Dawla Muhammad, a Daylamite military leader under the service of the Buyid amirate of Jibal.

His father, Rustam Dushmanziyar, had also served the Buyids, and was given lands in the Alborz to protect them against the local rulers of the neighbouring region of Tabaristan.

[11][12] Rustam was the uncle of Sayyida Shirin, a princess from the Bavand dynasty who was married to the Buyid amir (ruler) Fakhr al-Dawla (r. 976–980, 984–997).

At times Muhammad ibn Rustam Dushmanziyar acted as an ally of the Buyids; when Shams al-Dawla was faced with a revolt in Hamadan, for example, he turned to the Kakuyids for aid.
