The Battle of Kopychyntsi (Ukrainian: Битва під Копичинцями, Polish: Bitwa pod Kopyczyńcami; 12 May 1651) was fought between the Cossack Hetmanate and Crimean Khanate against the Polish–Lithuanian Commonwealth as a part of the Khmelnytsky Uprising.

In January 1651, the Zaporozhian Cossacks under the command of Hetman Bohdan Khmelnytsky launched an attack on the Bratslav Voivodeship of the Polish–Lithuanian Commonwealth and violated the Treaty of Zboriv which was signed in 18 August 1649.

The Crown Army led by Hetman Marcin Kalinowski came against them and starting a military campaign which lasted until September 1651, then the Treaty of Bila Tserkva was signed.

Hetman Marcin Kalinowski received an order from the Polish King John II Casimir to unite with the Crown Army forces numbered around 12,000 men[3] in Sokal.

Not finding the Crown Army there, Fylon Dzhalaliy started a siege of the city, Demko Lyzovets and Semen Savych moved on in pursuit of the Polish–Lithuanian Commonwealth’s forces.
