György Dózsa (or György Székely, 1470 – 20 July 1514) is a Székely man-at-arms (and by some accounts, a nobleman) from Transylvania, Kingdom of Hungary who leads a peasants' revolt against the kingdom's landed nobility.

He is eventually caught, tortured, and executed along with his followers, and remembered as both a Christian martyr and a dangerous criminal.

During the reign of king Vladislas II of Hungary (1490–1516), royal power declines in favor of the magnates, who use their power to curtail the peasants’ freedom.
