Suleyman Shah (Ottoman Turkish: سلیمان شاه; Modern Turkish: Süleyman Şah) was, according to Ottoman tradition, the son of Kaya Alp and the father of Ertuğrul and Gündogdu, who was, in turn, the father of Osman I, the founder of the Ottoman Empire. However, early Ottoman genealogies did not all agree on this lineage, some failing entirely to mention Suleyman Shah as one of Osman's ancestors. The connection between Osman I and Suleyman Shah may have been invented at a later date. His other son was Saru Yatı, the father of Bay Hodja. It is said that Suleyman Shah drowned in the river Euphrates in Syria. An Ottoman tomb in or near Qal'at Ja'bar has historically been associated with Suleyman Shah.
