Palatinate-Zweibrücken-Vohenstrauss-Parkstein was a state of the Holy Roman Empire based around Vohenstrauss and Parkstein in modern northeastern Bavaria, Germany. Palatinate-Zweibrücken-Vohenstrauss-Parkstein was created in 1569 out of the partition of the territories of Wolfgang of Palatinate-Zweibrücken for his fourth son Frederick. Frederick died in 1597 without heirs so Vohenstrauss-Parkstein was inherited by Palatinate-Neuburg.
