The Lacandón are one of the Maya peoples who live in the jungles of the Mexican state of Chiapas, near the southern border with Guatemala. Their homeland, the Lacandon Jungle, lies along the Mexican side of the Usumacinta River and its tributaries. The Lacandon are one of the most isolated and culturally conservative of Mexico's native peoples. Almost extinct in 1943, today their population has grown significantly, yet remains small, at approximately 650 speakers of the Lacandon language.
