The Bjelovar-Križevci County (Croatian: Bjelovarsko-križevačka županija; Hungarian: Belovár-Kőrös vármegye) was a historic administrative subdivision of the Kingdom of Croatia-Slavonia. Croatia-Slavonia was an autonomous kingdom within the Lands of the Crown of Saint Stephen (Transleithania), the Hungarian part of the dual Austro-Hungarian Empire. Its territory is now in northern Croatia. Belovár and Kőrös are the Hungarian names for the cities Bjelovar and Križevci, respectively. The capital of the county was Bjelovar.

The Bjelovar-Križevci County shared borders with the Hungarian county of Somogy, and the Croatian-Slavonian counties of Virovitica, Požega, Varaždin, and Zagreb. The river Drava formed its northeastern border. Its area was 5,048 km (1,949 sq mi) around 1910.

The territory of the Bjelovar-Križevci County was part of the Kingdom of Croatia when it entered a personal union with the Kingdom of Hungary in 1102, and with it Križevci County [hr] became part of the Habsburg monarchy in 1526. However, by then most of the territory of the later county had become part of Ottoman Hungary and remained so until the Treaty of Karlowitz in 1699. After that this area became part of the Military Frontier as the Varaždin Generalate, centred on Bjelovar, which was subdivided into the Križevci and Đurđevac districts.

Following the compromise of 1867 which established Austria-Hungary from the Austrian Empire several waves of administrative restructuring took place. In 1871 the Varaždin Generalate was dissolved and it territory integrated into Croatia-Slavonia. This territory, plus parts of the Križevci County and the Kutina exclave of Požega County were reconstituted as the Bjelovar and Križevci Counties. The remainder of the Croatian and Slavonian Military Frontiers were incorporated in 1881, which led to a final restructuring of the counties in 1886; Bjelovar-Križevci County was formed from almost all of the Bjelovar and Križevci Counties.

In 1920 by the Treaty of Trianon the county became part of the newly formed Kingdom of Serbs, Croats and Slovenes (later renamed to Yugoslavia) and was formally abolished in 1922 when the Vidovdan Constitution came into force. Since 1991, when Croatia became independent from Yugoslavia, the county has been part of Croatia.
