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

Her siblings included: Bernard of Świdnica, Henry I of Jawor, Bolko II of Ziębice and Judith, wife of Stephen I, Duke of Bavaria.

From this marriage, Beatrice and her siblings gained two half-siblings: Casimir of Koźle and Euphemia, wife of Konrad I of Oleśnica.

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 of Brandenburg and Count of Tyrol- and Stephen II – later Duke of Lower Bavaria.

She was one of two rival German queens, with Isabella of Aragon, wife of Frederick I. Beatrice died, at Munich, a long time before her husband's coronation as Holy Roman Emperor (in 1328).
