This page is a list of heirs to the Swedish throne.

Those who succeeded as King of Sweden are shown in bold.
In 1809 a coup d'état against King Gustav IV replaced him with his uncle Karl XIII. As the new king was childless, he and the ruling government arranged for the adoption of an heir to succeed him.
