Andreas Dudith (Croatian: Andrija Dudić Orehovički), also András Dudith de Horahovicza; * February 5, 1533 in Buda † February 22, 1589 in Wrocław), was a Hungarian nobleman of Croatian and Italian origin, bishop, humanist and diplomat in the Kingdom of Hungary.
Dudith was born in Buda, capital city of the Kingdom of Hungary to a Hungarian noble family with Croatian origin. His father, Jeromos Dudits, was a Croatian and his mother was an Italian. He studied in Wrocław, Italy, Vienna, Brussels and Paris.
In 1560 King Ferdinand I appointed him the bishop of Knin, Croatia. He then participated in the Council of Trent (1545–1563) where, in compliance with the wish of Ferdinand, he urged that the cup be given to the laity. Being appointed bishop of Pécs, Dudith went to Poland in 1565 as ambassador of Maximilian, where he married, and resigned his see, becoming an adherent of Protestantism. In Poland he began to sympathize with Socinian Anti-trinitarianism (the so-called Ecclesia Minor). Although he never declared himself officially a Unitarian, some researchers label him as one of the Anti-trinitarian thinkers.
After the election of Stephen Báthory as king of Poland, Dudith left Kraków and went to Wrocław and later to Moravia, where he supported the Bohemian Brothers.
Dudith maintained correspondence with famous Anti-trinitarians such as Giorgio Blandrata, Jacob Paleologus and Fausto Sozzini. Mihály Balázs, an expert on Central-European Anti-trinitarianism, affirms that Paleologus in Kraków lived in Dudić's house and departed from here to Transylvania. The theories of Blandrata, Sozzini and Ferenc Dávid had a great influence on him; nevertheless he always remained an Erasmian humanist, who condemned religious intolerance whether it came from Protestants or Catholics.
Dudith died in 1589 in Wrocław and was buried in the Saint-Elizabeth Lutheran Church.
