Sarukhan bin Alpagi (1300/01–1345/46) was a Turkish Bey of Magnesia (present-day Manisa, Turkey).
Sarukhan was a Turkish Emir who is remembered for his conquest in the Anatolian Peninsula. In 1313, he occupied Thyatira (present-day Akhisar, Manisa Province), and then left his name "Saruhan" to the region he had occupied, becoming an independent ruler and transmitting the region to his descendants.
At one point in 1336, Sarukhan formed an alliance with the Byzantine Emperor Andronicus the Younger, and supported him militarily in two sieges against the Genoese, in Mytilene and Phocaea. In 1341 however he attacked Constantinople with a fleet, but was repulsed around the Chersonesus in 1341.
