Chibcha, Mosca, Muisca, Muysca (*/ˈmɨska/), or Muysca de Bogotá was a language spoken by the Muisca people of the Muisca Confederation, one of the many indigenous cultures of the Americas. The Muisca inhabited the Altiplano Cundiboyacense of what today is the country of Colombia. The name of the language Muysc cubun in its own language means "language of the people", from muysca ("people") and cubun ("language" or "word"). Despite the disappearance of the language in the 17th century (approximately), several language revitalization processes are underway within the current Muisca communities. The Muisca people remain ethnically distinct and their communities are recognized by the Colombian state. Important scholars who have contributed to the knowledge of the Chibcha language include Juan de Castellanos, Bernardo de Lugo, José Domingo Duquesne and Ezequiel Uricoechea. In prehistorical times, in the Andean civilizations called preceramic, the population of northwestern South America migrated through the Darién Gap between the isthmus of Panama and Colombia. Other Chibchan languages are spoken in southern Central America and the Muisca and related indigenous groups took their language with them into the heart of Colombia where they comprised the Muisca Confederation, a cultural grouping.

In 1606 the entire clergy was ordered to provide religious instruction in Chibcha. The Chibcha language declined in the 18th century. In 1770, King Charles III of Spain officially banned use of the language in the region as part of a de-indigenization project. The ban remained in law until Colombia passed its constitution of 1991.
