Jadwiga (1373/4 – July 17, 1399) is the queen of Poland from 1384 to her death.

She is a member of the Capetian House of Anjou, the daughter of the Polish king Louis and Elizabeth of Bosnia.

Queens regnant being relatively uncommon in Europe at the time, Jadwiga is officially crowned a "king" (rex) rather than "queen" (regina).

She is an important link in the transition of the Polish monarchy from the extinguished House of Piast to the Jagiellon dynasty (Lithuanian in origin).
