Sibylle of Bavaria (16 June 1489 - 18 April 1519 in Heidelberg) was a member of the House of Wittelsbach was a princess of Bavaria-Munich and by marriage Electress Palatine.
Sibylle was the daughter of Duke Albert IV of Bavaria-Munich (1447–1508) from his marriage to Kunigunde of Austria (1465–1520), daughter of Holy Roman Emperor Frederick III. She married on 23 February 1511 in Heidelberg Elector Palatine Louis V (1478–1544). The couple had no children.
Louis had earlier been engaged to Sibylle's elder sister Sidonie, but Sidonie had died before she could marry, barely 17 years old.[1] The marriage was the starting point of the relaxation of the relations between Bavaria and the Palatinate, which were severely impacted by the Landshut War of Succession.[2] Relationships between the Palatinate and Emperor Maximilian I, who was Sibylle's uncle, also improved and Louis came closer politically to the Contra League.[3]
Sibylle died in 1519 and was buried in the Church of the Holy Spirit in Heidelberg. For a while, Sibylle's inheritance was claimed by her brother Ernest. This claim was denied by her widower and her brother William. Instead, Ernest was promised a high ecclesiastic office.[4]
