De chilenska schackmästerskapen har arrangerats sedan 1920. Till en början hölls tävlingarna vartannat år (ibland varje år, ibland med tre års uppehåll). Sedan 1948 har tävlingarna blivit årliga (med några få undantag: turneringar hölls inte 1963, 1967, 1973).
Tävlingen hålls under överinseende av Chiles nationella schackförbund (FENACH). Från 2004 till 2008 alternativa nationella mästerskap som anordnades av Chilenska schackförbundet (FEDACH) hölls.
Ledarna i antalet segrar i Chiles mästerskap är R. Flores (11) och M. Castillo (9).
