Sophia of Bavaria (; ; 1376 – 4 November 1428) was a Queen of Bohemia and the spouse of Wenceslaus, King of Bohemia and King of the Romans. She was briefly interim regent of Bohemia after the death of Wenceslaus in 1419.

Early life
Sophia was a member of the House of Wittelsbach and was the youngest child and only daughter of John II, Duke of Bavaria, and his spouse Catherine of Gorizia. Sophia's two brothers were Ernest, Duke of Bavaria, and William III, Duke of Bavaria.

Her paternal grandparents were Stephen II, Duke of Bavaria and his first wife Elisabetta of Sicily, daughter of Frederick III of Sicily and Eleanor of Anjou.  Sophia was a cousin of Isabeau of Bavaria, Queen of France. Sophia's maternal grandparents were Count Meinhard VI of Gorizia and Catharina of Pfannberg.

Sophia grew up in the care of her uncle, Frederick, Duke of Bavaria, in Landshut. Sophia liked hunting, which was one thing she had in common with her future husband. In 1388 uncle took her to Prague, where he worked through political negotiations to have his niece married off. He said that the twelve-year-old princess was impressed with Wenceslaus, moreover, the marriage was for political reasons. Sophia's father was represented in the negotiation of the marriage by her uncle Duke Frederick.

Queen 

On 2 May 1389 in Prague, Sophia married Wenceslaus, King of the Romans. Wenceslas and Sophia were probably married by the king's chancellor, Bishop Jan. Wenceslaus was in a dispute with the Archbishop of Prague, which threatened Sophia's coronation. She could have only been crowned queen by an archbishop.

Wenceslaus celebrated the marriage by making a number of excellent manuscripts such as the Wenceslas Bible. There was also a manuscript on marital fidelity. The relationship was described as happy. Sophia had no children.

Sophia's husband was certainly not an incompetent ruler, in chronicles he was described in a biased manner. Sophia is described as economically talented. In March 1393, her confessor John of Nepomuk died under torture. It was said that he died refusing to reveal her confession, but he was also at that time involved in a conflict with Jan of Jenštejn. During the rebellion and the imprisonment of her spouse in 1402–1403, she lived in Hradec Králové. Queen Sophia was initially a follower of Jan Hus and listened to his sermons, and like Wenceslas, she gave him her protection. After Hus was banned by the Pope in 1410, however, she withdraw her support. She was convinced that the death of Hus, in 1415, would lead to a riot.

Queen dowager regent 

Wenceslaus died in 1419. As a queen dowager, Sophia sought refuge with her brother-in-law, Sigismund of Hungary, whose claims on the throne of Bohemia she supported. For a period of time, Sophia was the official regent of Bohemia. 

In October 1419, the leading Bohemians signed a treaty with queen dowager Sophia with a promise to protect law and order. She soon lost authority, however. Sophia and Sigismund were involved in managing a property in Prešpurk together. There were rumours that Sophia and Sigismund had an affair. Sigismund remarked that the Queen dowager of Bohemia would surely marry again – possibly to Wladyslaw II of Poland.

Sophia died on 4 November 1428.
