The Malabar Coast, in historical contexts, refers to India's southwest coast, lying on the narrow coastal plain of Karnataka and Kerala states between the Western Ghats range and the Arabian Sea. The coast runs from south of Goa to Cape Comorin on India's southern tip.The Malabar Coast is also sometimes used as an all encompassing term for the entire Indian coast from the western coast of Konkan to the tip of the subcontinent at Cape Comorin. It is over 525 miles or 845 km long. It spans from the South - Western coast of Maharashtra and goes along the coastal region of Goa, through the entire western coast of Karnataka and Kerala and reaches till Kanyakumari. It is flanked by the Arabian Sea on the west and the Western Ghats on the east. The Southern part of this narrow coast is the South Western Ghats moist deciduous forests.

The Malabar Coast features a number of historic port cities, notably Kozhikode (Calicut), Cochin, and Quilon, that have served as centers of the Indian Ocean trade for centuries. Because of their orientation to the sea and to maritime commerce, the Malabar coast cities feel very cosmopolitan, and hosted some of the first groups of christians (now known as Syrian Malabar Nasranis), Jews (today called as Cochin Jews), and Muslims (at present known as Mappilas) in India.

Geographically, the Malabar Coast, especially on its westward-facing mountain slopes, comprises the wettest region of southern India, as the Western Ghats intercept the moisture-laden monsoon rains.
