Sophia Báthory (died 1680) was a niece of Gabriel Báthory. She married George Rákóczi II, Prince of Transylvania, on February 3, 1643. Prior to the marriage she was required by his mother to renounce Roman Catholicism in favor of Calvinism. This marriage united the Báthory and Rákóczi families. Francis I Rákóczi was Sophia and George's son. He was the only leading conspirator of the Wesselényi conspiracy whose life was spared, due to Sophia's intervention and a ransom payment. She also converted him to Catholicism. Sophia returned to Catholicism after her husband's death, and supported the Counter-Reformation.
