Battle of Korsuń (Ukrainian: Корсунь, Polish: Korsuń), (May 26, 1648) was the second significant battle of the Khmelnytsky Uprising. Near the site of the present-day city of Korsun-Shevchenkivskyi in central Ukraine, a numerically superior force of Cossacks and Crimean Tatars under the command of Hetman Bohdan Khmelnytsky and Tugay Bey attacked and defeated Polish–Lithuanian Commonwealth forces under the command of Hetmans Mikołaj Potocki and Marcin Kalinowski. As in the previous battle at Zhovti Vody, the outmanned Commonwealth forces took a defensive position, retreated, and were thoroughly routed by the opposing force.
