Zagreb County (Croatian: Zagrebačka županija) is a county in Northern Croatia. It surrounds, but does not contain, the nation's capital Zagreb, which is a separate territorial unit. For that reason, the county is often nicknamed "Zagreb ring" (Croatian: zagrebački prsten). According to the 2021 census, the county has 299,985 inhabitants, most of whom live in smaller urban satellite towns.
The Zagreb County once included the city of Zagreb, but in 1997 they separated, when the City was given a special status. Although separated from the city of Zagreb both administratively and territorially, it remains closely linked with it.
