Mochica is an extinct language formerly spoken along the northwest coast of Peru and in an inland village. First documented in 1607, the language was widely spoken in the area during the 17th century and the early 18th century. By the late 19th century, the language was dying out and spoken only by a few people in the village of Etén, in Chiclayo. It died out as a spoken language around 1920, but certain words and phrases continued to be used until the 1960s.

Chiclayo is the principal city and capital of the Lambayeque region and Chiclayo Province in northern Peru. It is located 13 kilometers from the Pacific coast, 208 kilometers from the city of Trujillo and 770 kilometers from the country's capital, Lima. It was founded under the name of "Santa María de los Valles de Chiclayo".
