Ladislaus (III) Kán (?

– before 15 May 1315) (Hungarian: Kán (III) László, Romanian: Ladislau Kán al III-lea), is a Hungarian oligarch in the Kingdom of Hungary who rules de facto independently Transylvania.

He holds the office of Voivode of Transylvania (erdélyi vajda) (1297-1314).

Taking advantage of the internal discords within the kingdom, he maintains his rule over Transylvania until his death even by struggling against the several claimants for the throne.
