The International Open Series (often referred to as Pontins International Open Series or PIOS for sponsorship reasons), was a series of snooker tournaments that ran from the 2001–02 season until the 2009–10 season. It was originally called the Open Tour but was renamed in 2005. The tour was established to provide players not on the Main Tour or the minor Challenge Tour (now WPBSA Q Tour) with some degree of professional competition, and the best performers were initially promoted to the Challenge Tour.
The series was abandoned after the 2009–10 season and replaced by Q School in the 2010–11 season.
