Mstislav Mikhailovich of Karachev

Mstislav Mikhailovich (1220–c. 1280) was a Rurikid prince, traditionally one of the younger sons of Mikhail Vsevolodovich of Chernigov and the founder of the Karachev branch of the Olgovichi.

Sixteenth-century genealogies assign him Karachev and Kozelsk, and he is counted as the first prince of Karachev, though many scholars regard Kozelsk as his actual seat. Genealogies name Svyatoslav, Tit and Andrei as his sons; Tit and Andrei also appear in chronicles.
