The WPA Asian Nine-ball Tour (also known as the Guinness Asian 9-Ball Tour or San Miguel Asian 9-Ball Tour for sponsorship reasons) was an annual series of nine-ball pool tournaments around East and Southeast Asia. The tour began in 2003, and is sanctioned by the World Pool-Billiard Association.
From 2003 to 2005, each leg had a field of 32 players and the total purse was US$50,000. In 2006, the number of players was reduced to 24 and total purse decreased to $40,000.
The winner in each leg of the tour receives a cash prize and points for the ranking for the yearly WPA World Nine-ball Championship.
San Miguel Beer and 188BET were the sponsor of the tournament prior to 2007, when this slot was taken over by Guinness.
