Bay of Bengal

Stretching between South and Southeast Asia, the Bay of Bengal has connected civilizations for thousands of years. Merchant ships, explorers, pilgrims, and traders have crossed its waters, making it one of the world's most historically significant maritime regions. Today, it remains essential to global trade, fisheries, biodiversity, and the economies of millions of people.

The Bay of Bengal is the northeastern arm of the Indian Ocean. It is bordered by Bangladesh to the north, India to the west, Myanmar to the east, and Sri Lanka and the Andaman and Nicobar Islands to the southwest. The bay receives water from some of Asia's largest rivers, including the Ganges, Brahmaputra, and Meghna, creating one of the world's largest delta systems.

Today, the Bay of Bengal supports international shipping, fishing industries, tourism, offshore energy exploration, and marine conservation while serving as an important transportation corridor linking South Asia with Southeast Asia and the wider Indo-Pacific region.
