Máté (III) Csák (between 1260-65 – 18 March 1321) (Hungarian: Csák (III) Máté, Slovak: Matúš Čák III), also Máté Csák of Trencsén (Hungarian: trencséni Csák (III) Máté, Slovak: Matúš Čák III Trenčiansky) is a Hungarian oligarch in the Kingdom of Hungary who rules de facto independently the northwestern counties of the kingdom (today roughly the western half of present-day Slovakia and parts of Northern Hungary).

He holds the offices of Marshal (főlovászmester) (1293–1296), Palatine (nádor) (1296–1297, 1301–1310) and master of the treasury (tárnokmester) (1310).

He maintains 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 is often described as a symbol of the struggle for independence in both the Hungarian and Slovak literatures.
