The Battle of Sablat, also called the battle of Záblatí in Czech, occurred on 10 June 1619 during the Bohemian period of the Thirty Years' War. The battle was fought between the Catholic army of Bucquoy and the Protestant army of von Mansfeldt.

When count Ernst von Mansfeldt was on his way to reinforce general Hohenloe, who was besieging Budweis, General Buquoy intercepted von Mansfeldt near the small village of Záblatí and brought him to battle. Von Mansfeldt suffered defeat, losing at least 1500 infantry and his baggage train.

As a result, the Bohemians had to lift the siege of Budweis.
