The De la Gardie campaign was a joint military campaign by the Tsardom of Russia and Sweden during the Polish–Russian War from April 1609 to June 1610.
Russia was unofficially occupied during the early Time of Troubles by the Polish–Lithuanian Commonwealth, which had supported False Dmitry II as the Tsar of Russia since 1607. Tsar Vasili IV formed a military alliance with Sweden in 1609, providing a 5,000-strong auxiliary corps commanded by Jacob De la Gardie and Evert Horn to support Russian forces under Mikhail Skopin-Shuisky. The De la Gardie campaign was successful against False Dmitry II, dispersing his court in Tushino – a former village and town to the north of Moscow, but failed against the Polish–Lithuanians and was defeated at the Battle of Klushino on 4 June 1610.

In return, Sweden would acquire Kexholm Country for all eternity. Muscovy must also pay the Swedish army at a price of 32,000 roubles month, which as calculated corresponded to 104,000 Reichsthalers. The Swedish army would operate in conjunction with a Muscovite army of some 3,000 men.
