Matthew (II) from the kindred Csák (Hungarian: Csák nembeli (II.) Máté; Slovak: Matúš Čák II; Romanian: Matei Csáki al II-lea; c. 1235 – 1283 or 1284) was a powerful Hungarian baron, landowner and military leader, who held several secular positions during the reign of kings Béla IV, Stephen V and Ladislaus IV. He was the first notable member of the Trencsén branch of the gens ("clan") Csák. His nephew and heir was the oligarch Matthew III Csák, who, based on his uncles' acquisitions, became the de facto ruler of his domain independently of the king and usurped royal prerogatives on his territories.
