Kaya Sultan (1633–1659) was an Ottoman princess. She was the daughter of Ottoman sultan Murad IV. She married the statesman Melek Ahmed Pasha in 1644 and died shortly after giving birth, at the age of 26, due to complications during her labour. The famed Ottoman traveler Evliya Çelebi noted a specific encounter with Kaya Sultan in his Book of Travels. An entire chapter of the book is dedicated to Kaya Sultan, from her pregnancy to her death.
