Sigismund Báthory was Prince of Transylvania several times between 1586 and 1602, and Duke of Racibórz and Opole in Silesia in 1598. His father, Christopher Báthory, ruled Transylvania as voivode of the absent prince, Stephen Báthory. Sigismund was still a child when the Diet of Transylvania elected him voivode at his dying father's request in 1581. Initially, regency councils administered Transylvania on his behalf, but Stephen Báthory made János Ghyczy the sole regent in 1585. Sigismund adopted the title of prince after Stephen Báthory died.

The Prince of Transylvania was the head of state of the Principality of Transylvania from the last decades of the 16th century until the middle of the 18th century. John Sigismund Zápolya was the first to adopt the title in 1570, but its use only became stable from 1576.
