Which Asian peninsula includes Vietnam, Laos, Cambodia, Thailand and Myanmar?

The Indochina Peninsula is the Asian peninsula that includes Vietnam, Laos, Cambodia, Thailand, and Myanmar.

It occupies mainland Southeast Asia between the Indian Ocean and the Pacific Ocean. The peninsula is commonly described as extending south from the Asian mainland, with the Malay Peninsula continuing farther toward Singapore and the Malay Archipelago.

The name Indochina reflects the region’s historical position between India and China and the influence of both civilizations. It is a geographic and cultural term, not the name of a single modern country. Definitions can vary slightly, especially over whether parts of southern China or the Malay Peninsula are included.

The peninsula contains major river systems, including the Mekong, Irrawaddy, Chao Phraya, and Red River. Its mainland countries have distinct languages, religions, and political histories despite their shared geographic setting.
