Feodor of Murom, also known as Yaroslav Svyatoslavich, was a 12th-century prince of Murom and Chernigov. As the son of the Kievan prince Svyatoslav Yaroslavich, he belonged to the Rurik dynasty and founded its Murom-Ryazan branch. His life involved significant political shifts, including participating in the Council of Liubech in 1097 and ruling over Murom before eventually moving to Chernigov. He is recognized as a saint in the Russian Orthodox tradition, sometimes being identified with other historical figures in hagiographical accounts.

Following the death of his brother Davyd in 1123, he transitioned to Chernigov, though he later faced political struggles regarding his rightful holdings.
