The Hungarian Cultural Days of Cluj (Hungarian: Kolozsvári Magyar Napok; Romanian: Zilele Culturale Maghiare din Cluj) is the largest Hungarian festival in Transylvania. It occurs annually on 19 August, being the date when Cluj-Napoca (Hungarian: Kolozsvár) reached city status, and on 20 August, king St. Stephen's day, as well as the whole week around these. The cultural city days have been held from 2010 on, being organized by the Treasure Cluj Association (Hungarian: Kincses Kolozsvár Egyesület) and its partner organizations.
