Quingnam (also misspelled Quignam), also called Pescadora (though this name is ambiguous) and Chimú, is an extinct, poorly attested Indigenous language formerly spoken by the Chimú people on the coast of northern Peru. After the Spanish conquest, the language went into decline and was extinct by 1763. It is virtually unknown, with a list of numerals, proper names and a few other scattered words constituting the only data on this language. The language has been historically conflated with Mochica, another extinct language spoken in coastal Peru, but is completely distinct and unrelated to it.
