The war against Sigismund (Swedish: Kriget mot Sigismund) was a war between Duke Charles, later King Charles IX and Sigismund, King of Sweden and Poland. Lasting from 1598 to 1599, it is also called War of Deposition against Sigismund, since the focus of the conflicts was the attempt to depose the latter from the throne of Sweden. The war eventually resulted in the deposition of Sigismund, with Duke Charles taking over the government and later also acceding to the throne.

When Stephen Báthory died in 1586, Sigismund Vasa, son of King John III and Catherine Jagiellonica, was elected king of the Polish–Lithuanian Commonwealth in an attempt to continue the Polish–Swedish alliance, the original purpose being to confront Ivan IV. Sigismund had sworn to cede Estonia to the Commonwealth.

When King John III died in 1592 his son Sigismund, King of Poland since 1587, acceded to the Swedish throne. Then conflicts arose. Duke Charles, the oldest living son of Gustav Vasa, did not approve the accession of Sigismund, his nephew and a Catholic, to the government of a realm that could just as well be his.
