Indonesian Chess Championship

The Indonesian Chess Championship is organized by PERCASI (Indonesian: Persatuan Catur Seluruh Indonesia), the Indonesian Chess Federation. PERCASI was established in 1948 in Yogyakarta, although its official founding date is August 17, 1950, when its statutes and bylaws were enacted. Its offices were moved to Jakarta in 1955.

The first Indonesian championship recognized by PERCASI was held in Solo in 1953, although there are claims of a national championship having taken place in Semarang in 1952. Ardiansyah holds the record for most championships won with five. Since 1978, a women's championship has been held concurrently with the open championship.
