The Polish–Swedish Wars were a series of wars between the Polish–Lithuanian Commonwealth and Sweden. Broadly construed, the term refers to a series of wars between 1563 and 1721. More narrowly, it refers to particular wars between 1600 and 1629. These are the wars included under the broader use of the term:

• the 16th century conflict sometimes referred to as the Livonian War (1558–83)
• the War against Sigismund, in 1598
• the war of 1600–29 (sometimes considered a part of the larger trans-European Thirty Years' War) which was twice interrupted by periods of truce and can be divided into:
  • the war of 1600–11
  • the war of 1617–18
  • the war of 1621–25
  • the war of 1626–29
