De chilenske mesterskaber i skak har været afholdt siden 1920. I starten blev konkurrencerne afholdt hvert andet år (nogle gange hvert år, nogle gange med en pause på tre år). Siden 1948 er konkurrencerne blevet årlige (med få undtagelser: turneringer blev ikke afholdt i 1963, 1967, 1973).
Konkurrencen afholdes i regi af Chiles nationale skakforbund (FENACH). Fra 2004 til 2008 alternative nationale mesterskaber arrangeret af det chilenske skakforbund (FEDACH) blev afholdt.
Førerne i antallet af sejre i Chiles mesterskaber er R. Flores (11) og M. Castillo (9).
