Vsevolod II Olgovich (Russian: Всеволод II Ольгович) (died August 1, 1146) was the Prince (Knyaz) of Chernigov (1127–1139) and Grand Prince (Velikiy Knyaz) of Kiev (1139–1146), son of Oleg Svyatoslavich, Prince of Chernigov.
Vsevolod married Maria, the daughter of Grand Duke Mstislav of Kiev. They had two sons and two daughters:
- Sviatoslav III of Kiev
- Yaroslav Vsevolodovich, born in 1139
- Anna of Chernigov, married a prince of Galicia 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.
