The Indian Open, titled for sponsorship reasons as the Hero Indian Open since 2011, is the national open golf championship of India, organised by the Indian Golf Union. Founded in 1964, it was added to the Asia Golf Circuit schedule in 1970. In 1998 it became an event on the rival Omega Tour (known as the Asian Tour since 2004). Since 2015, it has also been co-sanctioned by the European Tour. From 1964 until 2000, the tournament was held exclusively at either Delhi Golf Club or Royal Calcutta Golf Club. Since then it has been held at Classic Golf Resort in 2000 and 2001, Karnataka Golf Association in 2012, and DLF Golf and Country Club in 2009 and since 2017; all other editions have been held at Delhi Golf Club.
