Madgaon, town, west-central Goa state, western India. Madgaon is situated just inland from the Arabian Sea on the railway that extends from Marmagao port (northwest) to Castle Rock (east) in Karnataka state.
Madgaon is the second most populous urban area in Goa. It gained importance with the development of Marmagao port, the best harbor between Mumbai (Bombay; north) and Kochi (Cochin; south). An industrial estate just outside the city, a cold-storage plant for fish, and a large agricultural-produce market have strengthened its economic position. The city is not far from Colva, considered to have one of India’s most beautiful beaches. Pop. (2001) town, 78,382; urban agglom., 94,383; (2011) city, 87,650; urban agglom., 106,484.
