The Edict of Torda prohibits the persecution of individuals on religious grounds in John Sigismund Zápolya's Eastern Hungarian Kingdom.

The Edict of Torda was a decree that authorized local communities to freely elect their preachers in the Eastern Hungarian Kingdom of John Sigismund Zápolya. The delegates of the Three Nations of Transylvania – the Hungarian nobles, Transylvanian Saxons, and Székelys – adopted it at the request of the monarch's Antitrinitarian court preacher, Ferenc Dávid, in Torda on 28 January 1568. Though it did not acknowledge an individual's right to religious freedom, in sanctioning the existence of a radical Christian religion in a European state, the decree was an unprecedented act of religious tolerance.

John Sigismund Zápolya or Szapolyai was King of Hungary as John II from 1540 to 1551 and from 1556 to 1570, and the first Prince of Transylvania, from 1570 to his death. He was the only son of John I, King of Hungary, and Isabella of Poland. John I ruled parts of the Kingdom of Hungary with the support of the Ottoman Sultan Suleiman; the remaining areas were ruled by Ferdinand I of Habsburg, who also ruled Austria and Bohemia. The two kings concluded a peace treaty in 1538 acknowledging Ferdinand's right to reunite Hungary after John I's death, though shortly after John Sigismund's birth, and on his deathbed, John I bequeathed his realm to his son. The late king's staunchest supporters elected the infant John Sigismund king, but he was not crowned with the Holy Crown of Hungary.

The Eastern Hungarian Kingdom is a modern term coined by some historians to designate the realm of John Zápolya and his son John Sigismund Zápolya, who contested the claims of the House of Habsburg to rule the Kingdom of Hungary from 1526 to 1570. The Zápolyas ruled over an eastern part of Hungary, and the Habsburg kings ruled the west. The Habsburgs tried several times to unite all Hungary under their rule, but the Ottoman Empire prevented that by supporting the Eastern Hungarian Kingdom.
