Beatrice of Silesia (also known asBeatrice of Świdnica;Polish:Beatrycze świdnicka,German:Beatrix von Schweidnitz; 1290 – 24 August 1322) was a Polish princess member of theHouse of Piast in the Silesian branch ofJawor-Świdnica and by marriage Duchess of Bavaria and German Queen.

She was the second daughter ofBolko I the Strict, Duke of Jawor-Świdnica, by his wifeBeatrice, daughter ofOtto V, Margrave of Brandenburg-Salzwedel.[1][better source needed][2]
Beatrice was the third of ten children born to her mother and father. Her siblings included:Bernard of Świdnica,Henry I of Jawor,Bolko II of Ziębice and Judith, wife ofStephen I, Duke of Bavaria.
Seven years after the death of Beatrice's father and the birth of her posthumous sister, Anna, her mother Beatrice was remarried toWładysław of Bytom. From this marriage, Beatrice and her siblings gained two half-siblings:Casimir of Koźle and Euphemia, wife ofKonrad I of Oleśnica.
After her father's early death in 1301, Beatrice and her siblings were placed under the tutelage of their maternal uncleHerman, Margrave of Brandenburg-Salzwedel until 1305, when the oldest son of Bolko I, Bernard, assumed the government of his domains and the guardianship of his younger siblings, including Beatrix.
It was this brother Bernard who, wanting to secure an alliance with Bavaria, arranged Beatrice's marriage toLouis IV, Duke of Upper Bavaria. The wedding took place by 14 October 1308. During her marriage, Beatrice gave birth to six children, but only three survived to adulthood:Matilda -by marriage Margravine of Meissen-,Louis V the Brandenburger -later Duke of Upper Bavaria, Margrave ofBrandenburg and Count ofTyrol- andStephen II – later Duke ofLower Bavaria.
Duke Louis IV was electedGerman King on 20 October 1314. However, another faction had electedFrederick I of Austria as King on 19 October. The two rival Kings would continue their dispute for the rest of her life. She was one of two rival German queens, withIsabella of Aragon, wife of Frederick I.
Beatrice died, atMunich, a long time before her husband's coronation as Holy Roman Emperor (in 1328). Two years after her death, Louis IV was remarried toMargaret II, Countess of Hainaut.
Louis and Beatrix had six children; three of them lived to adulthood:
