Greater Cochin is the metropolitan urban agglomeration centred on the city of Kochi (formerly Cochin) in the Ernakulam district of the Indian state of Kerala. It comprises the Kochi Municipal Corporation along with several adjoining municipalities, panchayats and census towns that together form one of the largest urban regions on the south-western coast of India.

Geography
Greater Cochin lies along the Malabar Coast, around the natural harbour formed at the confluence of several backwater channels and the Arabian Sea. The agglomeration spans the mainland around Ernakulam, the islands of the Vembanad estuary including Willingdon Island, Vypin and Bolgatty, and the historic peninsula of Fort Kochi–Mattancherry. The terrain is largely low-lying, intersected by canals, lagoons and the northern reaches of the Vembanad Lake.
Composition
The metropolitan region is administered by multiple local bodies, with the Kochi Municipal Corporation at its core. Surrounding municipalities such as Tripunithura, Kalamassery, Aluva, Angamaly, Perumbavoor, Eloor, Maradu, Thrikkakara, Thripunithura and Paravur, together with several gram panchayats, contribute to the agglomeration. Spatial planning for the region is coordinated by the Greater Cochin Development Authority (GCDA), constituted by the Government of Kerala, and the Goshree Islands Development Authority (GIDA) for the island clusters.
Background and history
Cochin developed as a major port after the silting of Kodungallur in 1341, which opened the natural harbour at the present site. The port saw successive Portuguese (from 1500), Dutch (from 1663) and British (from 1795) influence, leaving a layered colonial heritage in Fort Kochi and Mattancherry. The modern harbour was engineered in the early twentieth century under Sir Robert Bristow, leading to the creation of Willingdon Island. The princely state of Cochin merged with Travancore in 1949, and the territory became part of Kerala on the linguistic reorganisation of states in 1956. The municipal corporation of Cochin was constituted in 1967 by amalgamating the municipalities of Fort Cochin, Mattancherry and Ernakulam with adjoining panchayats, providing the institutional basis for the term "Greater Cochin".
Economy
The Greater Cochin region is the principal commercial and industrial hub of Kerala. Key economic anchors include:

Transport
Greater Cochin is served by the Cochin International Airport at Nedumbassery, the first airport in India built under a public–private partnership and the first fully solar-powered airport in the world. Rail connectivity is provided primarily by Ernakulam Junction and Ernakulam Town stations on the Southern Railway. Urban transport includes the Kochi Metro, inaugurated in 2017 and operated by the Kochi Metro Rail Limited, and the Kochi Water Metro, a backwater-based ferry network launched in 2023.
