Devletşah Sultan Hatun (دولت شاه خاتون سلطان, "reign of the Şah" or "sovereign of the reign", c. 1365 - 23 January 1414), was the daughter of Süleyman Şah Bey, the ruler of the Germiyanids. She was a consort of Sultan Bayezid I of the Ottoman Empire.

Devletşah Hatun was born to an Anatolian prince, Süleyman Şah Bey, the ruler of the Germiyanids. Her mother Mutahhare Abide Hatun was a granddaughter of Mawlānā Jalal al-Din Muhammad Rumi, the founder of the Sufi order of Mevlevis, through his son Sultan Walad. She had three full-brothers, Ilyas Pasha, Hızır Pasha and Qurd Abdal.

Marriage
In 1378, Süleyman Şah, sent an envoy to sultan Murad I, proposing a marriage between his daughter, Devletşah Hatun and his son Bayezid. He wished to protect his territory against the invasions of the Karamanids, had proposed this marriage and had offered, as a dowry to his daughter, Kütahya, his seat of power and several other Germiyan cities. Murad agreed and acquired most of the principality.

The chroniclers testify of the riches that was displayed during the wedding feast. Envoys from the Karamanids, Hamidoğu, Mentesheoğlu, Saruhanids, Isfendiyarids and an envoy of the Mamluk sultan were all present at the wedding feast.

During the wedding feast, the envoy of Hüseyin Bey, the ruler of the Hamidili principality, offered to sell his beylik to Murad. When, afterwards, Murad came to Kütahya, Hüseyin Bey sent his envoy to conclude the formalities of the sale.
