The Chinchorro mummies are mummified remains of individuals from the South American Chinchorro culture, found in what is now northern Chile. They are the oldest examples of artificially mummified human remains, having been buried up to two thousand years before the Egyptian mummies. The earliest mummy that has been found in Egypt dated around 3000 BCE, while the oldest anthropogenically modified Chinchorro mummy dates from around 5050 BCE.

The oldest naturally mummified corpse recovered from the Atacama Desert is dated around 7020 BCE.

Shell midden and bone chemistry suggest that 90% of the people's diet was seafood. Many ancient cultures of fisherfolk existed, tucked away in the arid river valleys of the Andes, but the Chinchorro made themselves unique by their dedicated preservation of the dead.

The Chinchorro culture settlements and artificial mummification process in Arica and Parinacota were declared a World Heritage Site by UNESCO in 2021.
