Kobilska Planina ({{langx|bg|Кобилска планина}}) is a mountain range in Kraishte region in western Bulgaria. It is part of the Milevska–Konyavska mountain chain system.

Kobilska is situated between the valley of the Treklyanska reka, a right tributary of the river Struma, that separates it from the Penkyovska Planina to the northeast, the valley of the Dobridolska reka, a right tributary of the Treklyanska reka, that separates it from the Zemenska Planina to the southeast, and the valley of the Bazovichka reka, a right tributary of the Treklyanska reka, that separates it from the Milevska Planina to the north and northwest. To the west a 1,148 m saddle links it to the Izvorska Planina. Its length is about 10 km; the width is 6 km. The highest summit is Beli Kamak (1,356 m), situated 2 km west of the village of Gabreshevtsi.
