Palatinate-Kleeburg was an imperial state of the Holy Roman Empire, centered on the Alsatian lordship of Kleeburg.
It was the younger partition of Palatinate-Zweibrücken in 1604 for John Casimir, youngest son of John I, Count Palatine of Zweibrücken. His marriage to Catherine of Sweden, eldest surviving daughter of King Charles IX of Sweden, would eventually see his elder son and successor Charles Gustav succeeded to the Swedish throne in 1654, giving Palatinate-Kleeburg to Adolph John I, his younger brother. In 1718, Gustav, Count Palatine of Zweibrücken inherited the Duchy of Zweibrücken and its seat in the Imperial Diet. After his death in 1731, Palatinate-Kleeburg was passed to Palatinate-Zweibrücken-Birkenfeld.
