Savcı Bey is a fourteenth-century Ottoman prince who participates in a joint rebellion with the East Roman (Byzantine) prince Andronikos against both of their fathers, the Ottoman emperor Murad I and the East Roman (Byzantine) emperor John V Palaiologos, respectively, in the 1370s.
Savcı is the youngest of Murad I's three sons.
The name of his mother and birth year are unknown.
In Ottoman tradition, all princes (Turkish: şehzade) are required to serve as provincial (sanjak) governors as a part of their training.
Savcı's sanjak is Bursa, the co-capital of the empire (along with Edirne).
