The siege of Tre Kronor (Swedish: Belägring av Tre Kroner, Danish: Belejringen af Tre Kroner), or the siege of the Royal Castle in Stockholm, was a siege of the Tre Kronor Castle in Stockholm lasting from 17 October 1501 to 9 May 1502 between the Kalmar Union and Sten Sture the Elder's Swedish rebellion. The besieged unionists would suffer from food shortages, and Queen Christina of Saxony would issue a surrender on 5 May 1501 and would leave the castle on 9 May.
