The Isthmus of Tehuantepec is an isthmus in southern Mexico between the Gulf of Mexico and the Pacific Ocean. It represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. The isthmus is connected to Veracruz, Mexico City, and the Guatemalan border by rail.

The Isthmus of Tehuantepec is an isthmus in southern Mexico between the Gulf of Mexico to the north and the Pacific Ocean to the south. It represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. The isthmus is connected to Veracruz, Mexico City, and the Guatemalan border by rail.

Prior to the opening of the Panama Canal, the isthmus was a major shipping route, known simply as the Tehuantepec Route. A railroad extending 192 miles (310 km) from Coatzacoalcos, on the Gulf of Campeche, to Salina Cruz, on the Gulf of Tehuantepec, was opened in 1907. The Tehuantepec railway (now the Ferrocarril Transístmico) or "Trans-Isthmic Railroad" also includes a branch of 29 km (18 mi) between Juile and San Juan Evangelista.

The population is composed almost wholly of indigenous Zapotec peoples. The women are the traders in Tehuantepec and do little menial work. Known as "Tehuanas", these women are known throughout Mexico for their colorful dresses, assertive personalities, and relatively equal relations with men, leading some to characterize them as "matriarchal".

The predominant climates in the region are tropical savanna (primarily in the south) and tropical monsoon (primarily in the north). There are also small central areas with a temperate climate due to elevation.

The narrowness of the isthmus, and the gap in the Sierra Madre, allow the trade winds from the Gulf of Mexico to blow through to the Pacific. Normally, these winds are not particularly strong, but periodically, a surge of denser air originating from the North American continent will send strong winds through the Chivela Pass and out over the Gulf of Tehuantepec on the Pacific coast. This wind is known as the Tehuano.
