Hrvatsko zagorje (meaning Croatian upland or hinterland) is a historic region north of Zagreb, Croatia. It comprises the whole area north of Medvednica mountain up to Slovenia in the north and west, and up to the regions of Međimurje and Podravina in the north and east. Zagorje was split into Krapina-Zagorje county and a part of Varaždin county after the establishment of the independent Republic of Croatia. Croatian people usually refer to this region as "Zagorje". However, due to another region in Slovenia, which bears the same name, the Croatian part is also called "Hrvatsko zagorje" (meaning Croatian Zagorje). If one also considers linguistic and other factors, the Croatian capital of Zagreb could also be counted to this region.

The town of Krapina is often referred to as the cultural capital of the Kajkavian language (a dialect of the Croatian language). Every year, the Festival of Kajkavian Song (Festival kajkavske popevke) takes place in Krapina.
