Gir Somnath is a district of Gujarat, India. It is located on the southern corner of the Kathiawar peninsula with its headquarters at the city of Somnath.

Kathiawar is a peninsula, near the far north of India's west coast, of about 61,000 km2 (23,500 sq mi) bordering the Arabian Sea. It is bounded by the Gulf of Kutch in the northwest and by the Gulf of Khambhat in the east. In the northeast, it is connected to the rest of Gujarat and borders on the low, fertile hinterland of Ahmedabad. It is crossed by two belts of hill country and is drained radially by nine rivers which have little natural flow aside from in monsoon months, thus dams have been built on some of these. Kathiawar ports have been flourishing centres of trade and commerce since at least the 16th century.
