贝尔梅霍河（Río Bermejo）是南美洲不能让船只航行的河流，河道全长1,450公里。

贝尔梅霍河自玻利维亚塔里哈附近的发源地往东南方向流动，成为阿根廷和玻利维亚的接壤边境，最后流入阿根廷巴拉圭河。

The Bermejo River (Spanish, Río Bermejo) is a river in South America that flows from Bolivia to the Paraguay River in Argentina. The river is generally called Bermejo in spite of its different names along its way, but it also has its own Native American names; in Wichí it is called Teuco, and in Guaraní it is called Ypitá. In the plains of Argentina's Gran Chaco the Bermejo forms wetlands and splits into two branches. The southern branch is the bed of the old Bermejo River, now an intermittent stream called Río Bermejito. The northern branch is now the main stem of the Bermejo and is called the Teuco River (Río Teuco), Bermejo Nuevo, or simply the Bermejo River. The two branches rejoin at 25°39′S 60°11′W / 25.650°S 60.183°W / -25.650; -60.183, near Villa Río Bermejito, forming the Lower Bermejo River.
