The title grand prince or great prince (Latin: Magnus Princeps; Belarusian: Вялíкі князь, 'Vyaliki knyaz'; German: Großfürst; Finnish: Suuriruhtinas; Danish: Storfyrste; Russian: Великий князь, Velikiy knyaz; Swedish: Storfurste; Croatian: Veliki knez; Serbian: veliki župan/велики жупан; Lithuanian: Didysis kunigaikštis; Hungarian: Nagyfejedelem; Czech: Velkokníže; Polish: Wielki książę; Turkish: Büyük prens, Granprens, Ukrainian: Великий князь, Velykyi kniaz) ranked in honour below emperor and tsar and above a sovereign prince (or Fürst).

Grand duke is the usual and established, though not literal, translation of these terms in English and Romance languages, which do not normally use separate words for a "prince" who reigns as a monarch (e.g. Albert II, Prince of Monaco) and a "prince" who does not reign, but belongs to a monarch's family (e.g. Prince William, Duke of Cambridge). German, Dutch, Slavic and Scandinavian languages do use separate words to express this concept, and in those languages grand prince is understood as a distinct title (for a cadet of a dynasty) from grand duke (hereditary ruler ranking below a king).

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:

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.
