Louis II the Younger (German: Ludwig II. der Jüngere) (14 September 1502 - 3 December 1532) was the Duke of Zweibrücken from 1514 until 1532.
Louis was born in Zweibrücken in 1502 as the eldest son of Alexander, Count Palatine of Zweibrücken, and succeeded his father in 1514. He became involved in the Reformation as it emerged and was influenced by Johannes Bader. At the Imperial Diet of Worms in 1521 he encountered Martin Luther. In 1523 he appointed Johann Schwebel the high chaplain of Zweibrücken. He failed in his attempts against the Abbeys of Hornbach and Wörschweiler. In 1529 he made possible the Swiss Marburg Colloquy by enabling German Protestant theologians the ability to bypass the territories of the Archbishopric of Mainz and the Bishoprics of Speyer and Worms.
Louis died of tuberculosis in Zweibrücken in 1532 and was buried in the Alexanderskirche. Due to the minority of his son and heir Wolfgang, the regency of Palatinate-Neuburg was passed to his younger brother Rupert.
