Count Palatine Gustav Samuel Leopold of the House of Wittelsbach (12 April 1670, Stegeborg Castle near Söderköping, Sweden – 17 September 1731, Zweibrücken, Germany) was the Count Palatine of Kleeburg from 1701 until 1731 and the Duke of Zweibrücken from 1718 until 1731. His titles included: 5th Duke of Stegeborg (in Sweden),Count Palatine of the Rhine, and Duke in Bavaria.

He was the last male member of the Kleeburg line of the House of Wittelsbach to reign.

Gustavus Samuel Leopold was born at Stegeborg Castle near Söderköping in 1670 as the youngest son of Adolph John I, Count Palatine of Kleeburg. The siblings were reportedly badly treated by their parents, and in 1687, Gustav helped his sisters Catherine and Maria Elizabeth to escape from their parents to the protection of the Swedish royal court, which became a scandal in contemporary Sweden.

He succeeded his brother Adolph John II as Count Palatine of Kleeburg in 1701, and his cousin Charles XII, King of Sweden, as Duke of Zweibrücken in 1718. The king's death also made him one of the eligible candidates for the Swedish throne. From 1720 until 1725 he moved his residence to a palace, Schloss Zweibrücken, built by Jonas Erikson Sundahl.

Gustavus Samuel Leopold died in Zweibrücken in 1731 and was buried in the Alexanderkirche. As the last male member of his branch of the House of Wittelsbach, his territories were inherited by Christian III, Count Palatine of Zweibrücken-Birkenfeld.
