The siege of Zbarazh (Ukrainian: Облога Збаража, Битва під Збаражем, Polish: Oblężenie Zbaraża, Bitwa pod Zbarażem; 10 July — 22 August, 1649) was fought near the site of the present-day city of Zbarazh in Ukraine between the Cossack Hetmanate and Crimean Khanate against the Polish–Lithuanian Commonwealth as a part of the Khmelnytsky Uprising. The siege lasted for seven weeks.

The Polish–Lithuanian Commonwealth’s forces were besieged in the Zbarazh Castle until in the aftermath of the Battle of Zboriv on 15–16 August 1649 and the Treaty of Zboriv on 18 August 1649. The Volhynian towns of Zbarazh and Zboriv are roughly neighboring one another.
