Battle of Pyliavtsi (; ); September 23, 1648) was the third significant battle of the Khmelnytsky Uprising. Near the site of the present-day village of Pyliava, which at that time belonged to the Kingdom of Poland, and now lies in south-central Ukraine, Polish-Lithuanian Commonwealth forces met a numerically superior force of Cossacks and Crimean Tatars under the command of Bohdan Khmelnytsky and Tugay Bey. The Commonwealth forces were dealt a third consecutive defeat.
