Cecilia Rozgonyi (1398–1434) was a Hungarian noble.
She was the daughter of Peter Szentgyörgyi, an influential Hungarian nobleman. She married another member of the kingdom's elite, Stephen Rozgonyi, and had three sons with him: John, Stephen, and Emeric.
Cecilia Rozgonyi became famous for her struggle against the Ottoman Empire under King Sigismund of Hungary at Golubac fortress in 1428, commanding her own ship. When the army was retreating Sigismund was attacked and Cecilia intervened, saving the life of the Hungarian king.
