Konkan is the rugged section of the mid-western coast of India, the coastal hinterland of Konkan consists of numerous riverine islands, river valleys, and the hilly slopes of the Western Ghats, that lead up into the tablelands of the Deccan. Geographically, Konkan is bound by the Arabian Sea to the west, the Deccan Plateau to the east. The coast of Konkan proceeds from the north at Damaon in the Gulf of Cambay, extends southwards all along the western seaside areas of Maharashtra and Goa, and meets the Canara coast at the northern edge of Carwar district in Karnataka.

According to the Sahyadrikhanda of the Skanda Purana, Parashurama threw his axe into the sea and commanded the Sea God to recede up to the point where his axe landed. The new piece of land thus recovered came to be known as Saptah-Konkana, meaning "piece of earth", "corner of earth", or "piece of corner", derived from Sanskrit words: koṇa (कोण, corner) + kaṇa (कण, piece). Xuanzang, the noted Chinese Buddhist monk, mentioned this region in his book as Konkana Desha; Varahamihira's Brihat-Samhita described Konkan as a region of India; and 15th century author Ratnakosh mentioned the word Konkandesha.
