Confederated sejm () was a form of sejm in the Polish–Lithuanian Commonwealth in the 18th century. After 1764, sejms were frequently confederated. Under rules of confederation, decisions were made by the majority of deputy votes cast, and so the privilege of liberum veto did not apply. Examples of confederated Sejms: Repnin Sejm, Great Sejm.
