Vsevolod II Olgovich (died August 1, 1146) was Prince of Chernigov (1127–1139) and Grand Prince of Kiev (1139–1146). He was a son of Oleg Svyatoslavich, Prince of Chernigov.
Vsevolod married Maria Mstislavna of Kiev, the daughter of Grand Duke Mstislav of Kiev. They had two sons and two daughters:
Yaroslav II Vsevolodovich, born in 1139
Anna of Chernigov, married a prince of Halych, son of Vasylko Rostyslavych according to some chronicles
Zvenislava of Chernigov, married Boleslaw I the Tall, Duke of Wroclaw
Though he had two sons, Vsevolod's chosen successor was his brother, Igor, and he obtained pledges from his subjects to accept Igor as his heir. According to one account, Vsevolod even had the Kievans kiss the Holy Cross and swear loyalty to Igor, which they resented. Shortly before his death, Vsevolod became a monk under the name Gavriil.
