The Linköping Bloodbath takes place on Maundy Thursday in Linköping, Sweden.

The Linköping Bloodbath (Swedish: Linköpings blodbad) on 20 March 1600 was the public execution by beheading of five Swedish nobles in the aftermath of the War against Sigismund (1598–1599), which resulted in the de facto deposition of the Polish and Swedish King Sigismund III Vasa as king of Sweden. The five were advisors to Catholic Sigismund or political opponents of the latter's uncle and adversary, the Swedish regent Duke Charles.
