Máté Csák or Matthew III Csák, also Máté Csák of Trencsén, was a Hungarian oligarch who ruled de facto independently the north-western counties of Medieval Hungary. He held the offices of master of the horse (főlovászmester) (1293–1296), palatine (nádor) and master of the treasury (tárnokmester) (1309–1311). He was able to maintain his rule over his territories even after his defeat at the Battle of Rozgony against King Charles I of Hungary. In the 19th century, he was often described as a symbol of the struggle for independence in both the Hungarian and Slovak literatures.

The Palatine of Hungary was the highest-ranking office in the Kingdom of Hungary from the beginning of the 11th century to 1848. Initially, Palatines were representatives of the monarchs, later the vice-regent (viceroy). In the early centuries of the kingdom, they were appointed by the king, and later were elected by the Diet of the Kingdom of Hungary. A Palatine's jurisdiction included only Hungary proper, in the Kingdom of Croatia until 1918 the ban held similar function as the highest office in the Kingdom, monarch's representative, commander of the royal army and viceroy.
