Sayyida Shirin (Persian: سیده ملک خاتون‎), also simply known as Sayyida, was a Bavandid princess, who was the wife of Buyid ruler of Ray, Fakhr al-Dawla. She was the de facto ruler of Ray during the reign of her son, Majd al-Dawla (r. 997–1029).

According to the medieval historian Hilal al-Sabi' and the modern historian Madelung, Sayyida Shirin was the sister of the Bavandid ruler al-Marzuban. However, according to the Qabus-nama made by the Ziyarid ruler Keikavus (who was a neighbor of the Bavandids and of Bavandid descent himself), Sayyida Shirin was the niece of al-Marzuban.Hugh N. Kennedy calls her the son of a certain Bavandid ruler (ispahbadh) of Tabaristan named Sharwin, who may be the Bavandid ruler Sharwin III, who was the brother of al-Marzuban. Sayyida Shirin also had a brother named Rustam Dushmanziyar, whose son Muhammad ibn Rustam Dushmanziyar became the founder of the Kakuyid dynasty.

Although Sayyida is called a Kurd in some sources, she is generally agreed to be from the Bavand dynasty, which was of Dailamite origin.Encyclopædia Iranica also states that; “it should be remembered that “Kurd” in the sources of the 10th-11th centuries refers to all the transhumants of the Zagros region including the Lors.”
