Bilogora[a] is a low mountainous range and a microregion in Central Croatia.

It consists of a series of hills and small plains some 80 kilometres in length stretching in the direction northwest–southeast, along the southwest part of the Podravina region.

The highest peak is called Rajčevica (309 m), located in the north of the mountain.

Bilogora is considered to be the lowest mountainous region in Croatia, but is also the largest in terms of area.

Hinko Hranilović also wrote that "the name of Bilogora could come from the white and gray soil, which is formed by marls and sands, giving it the name "Bijela gora" or "Bjelogora" meaning white mountain, Which could indicate the origins of the name Bilogora could be extremely similar to the city of Bjelovar to its south.The Croatian Meteorological and Hydrological Service has a measuring station on Bilogora.
