Palatinate-Birkenfeld-Bischweiler was a state of the Holy Roman Empire based around Bischwiller. It was formed in 1600, after the separation from Palatinate-Zweibrücken-Birkenfeld and was incorporated into Palatine Zweibrücken in 1731.
Palatinate-Birkenfeld-Bischweiler was partitioned from Palatinate-Zweibrücken-Birkenfeld in 1600 for Christian I, the youngest son of Count Palatine Charles I. The state was partitioned into itself and Palatinate-Birkenfeld-Gelnhausen in 1654. In 1671 Count Palatine Christian II inherited Palatinate-Zweibrücken-Birkenfeld and this state ceased to exist.
