The mummies found from the Ancon and Zepita necropolis have evidence that this culture expanded far north up to the Chillón valley.

The Chancay culture took place between 1300 and 1450 A.D and after that became part of the Inca Empire.

Chancay was founded by Luis Flores, according to the viceroy Diego López de Zúñiga, 4th Count of Nieva, on November 16, 1562.

By then its name was Villa de Arnedo in memory of the fee he had in Spain.

By the time of Peru's independence, the April 16, 1828 law was created by the people of Chancay, and that made the town a "faithful town" In 1966, a 6.2 magnitude earthquake caused great damage in the north of Chancay and part of the Lima-Callao area.
