Neighboring States and International Border of Bihar

Bihar is one of India’s most historically significant states and occupies an important position in the eastern part of the country. Understanding Bihar’s neighbouring states and international borders is an essential topic for students preparing for competitive examinations such as BPSC, Bihar Police, SSC, Railway, UPSC, and other state-level tests.

Situated in the fertile Indo-Gangetic Plain, Bihar shares its borders with three Indian states and one international country. These boundaries have played a major role in shaping Bihar’s trade, migration, culture, and administration throughout history.

Geographical Location of Bihar

Bihar lies in eastern India and covers an area of approximately 94,163 square kilometres. The state capital is Patna, located near the banks of the River Ganga, which divides Bihar into northern and southern regions.

The state is strategically positioned between the Himalayan foothills to the north and the plains of eastern India to the south. Its location makes it a significant gateway connecting northern India with the eastern and northeastern regions.
