Svyatoslav Mstislavich of Karachev

Svyatoslav Mstislavich (died 1310) was a Rurikid prince of Karachev, the second son of Mstislav Mikhailovich, from whom he inherited Karachev. He appears in the sources only once: the Nikon Chronicle records that in 1310 Bryansk troops with a Golden Horde force seized Karachev, and Svyatoslav was killed.

He may have laid claim to Bryansk, by then held by the Smolensk branch of the Rurikids. He left no heirs.
