Joseph Charles, Hereditary Prince of Sulzbach (German: Joseph Karl; Sulzbach, 2 November 1694 – Oggersheim, 18 July 1729) was the eldest son of Theodore Eustace, Count Palatine of Sulzbach.
The Sulzbach line was related to the Palatinate-Neuburg line who were Electors Palatine. The Elector of the Palatinate Charles III Philip failed to produce a legitimate male heir, as did his brothers. Joseph Charles, the eldest son of the Count Palatine of Sulzbach, was the heir apparent. On 2 May 1717 Joseph Charles married Countess Palatine Elizabeth Augusta Sophie of Neuburg (1693–1728), the daughter of Charles III Philip, a match intended to unite the two lines and prevented another succession war.
However, all the sons fathered by the couple died in infancy and only three daughters survived. In 1728 Elizabeth Augusta died in childbirth and Joseph Charles died the following year in Oggersheim. Therefore, the inheritance of Palatinate-Sulzbach and the eventual inheritance passed to Joseph Charles' brother John Christian Joseph and his family.
Joseph Charles was buried in the St. Michael's Church, Munich.
