Philip Louis (2 October 1547 - 22 August 1614) was the Duke of Neuburg from 1569 until 1614.
Philip Louis was born in Zweibrücken in 1547 as the eldest son of Wolfgang, Count Palatine of Zweibrücken. After his father's death in 1569, his lands were partitioned between Philip Louis and his four brothers - Philip Louis received the Duchy of Neuburg. He married Anne of Cleves, daughter of Duke William IV of Jülich-Cleves-Berg, in 1574 and used the marriage as the basis of his claim to inherit the duchies in the succession controversy after Duke William's heirless death against the Elector of Brandenburg. The controversy threatened to spark a European War but the murder of King Henry IV of France defused the situation. In 1613 Philip Louis converted to Catholicism and gained the support of Spain and the Catholic League while Brandenburg received the support of the Netherlands. By the Contract of Xanten in 1614 it was partitioned without war: Philip Louis received the Duchies of Jülich and Berg.
Philip Louis died in Neuburg in 1614 and was buried in Lauingen.
