Čakovec Castle or Zrinski Castle is a medieval fortification in the middle of the town of Čakovec, the administrative seat of Međimurje County, northern Croatia.
The castle is located in the Zrinski Park, not far from the city's central square, and is the biggest fortification in Međimurje County. It was constructed of hewn stone and red brick, and, during its more than 7-century-long history, subjected to several reconstructions. Today it is partly restored.
The castle's main palace houses the Međimurje County Museum, the biggest museum in the county, and its atrium is also used as an outdoor theatre during the summer months. The place was the scene of the Zrinski-Frankopan conspiracy, a significant event in the history of Croatia.
