The Chuj or Chuh are a Maya people, whose homeland is in Guatemala and Mexico. Population estimates vary between 30,000 and over 60,000. Their Indigenous language is also called Chuj and belongs to the Q'anjobalan branch of Mayan languages. Most Chuj live in the Guatemalan department of Huehuetenango, in the municipalities of San Mateo Ixtatán and San Sebastián Coatán, with small numbers also residing in the neighboring border areas of the Mexican state of Chiapas. Los Angeles is believed to have a relatively large population of undocumented Chuj immigrants.

The Chuj, and their ancestors, are believed to have lived in the same area for 4,000 years. They first came into contact with Spanish conquistadores in the 1530s; however, they were not finally subdued by the Spanish colonial authorities until the 1680s. In the post-Colonial era, the Chuj lost much of their communal land, reducing them to extreme poverty. This resulted in a history of violent resistance to authority culminating in guerrilla activity against Guatemala's military junta in the 1980s.

Chuj (Spanish: [tʃux]) is a Mayan language spoken by around 40,000 members of the Chuj people in Guatemala and around 3,000 members in Mexico. Chuj is a member of the Qʼanjobʼalan branch along with the languages of Tojolabʼal, Qʼanjobʼal, Akateko, Poptiʼ, and Mochoʼ which, together with the Chʼolan branch, Chuj forms the Western branch of the Mayan family. The Chujean branch emerged approximately 2,000 years ago. In Guatemala, Chuj speakers mainly reside in the municipalities of San Mateo Ixtatán, San Sebastián Coatán and Nentón in the Huehuetenango Department. Some communities in Barillas and Ixcán also speak Chuj. The two main dialects of Chuj are the San Mateo Ixtatán dialect and the San Sebastián Coatán dialect.

The Chuj language has been influenced by Spanish, and Chuj speakers have a tendency to borrow Spanish words or code-mix. It is estimated that 70% of the Chuj language is purely Chuj. There are language conservation and revitalization efforts taking place in San Mateo Ixtatán, through groups like the Academia de Lenguas Mayas de Guatemala.
