The SemGroup Championship was a golf tournament for professional female golfers that was part of the LPGA Tour.
John Q. Hammons Hotels & Resorts was the title sponsor from 2003 to 2006.
In 2007, SemGroup, a Tulsa-based firm providing diversified services for end users and consumers of energy products, took over as the title sponsor.
SemGroup filed for bankruptcy protection in July 2008; in November 2008, the LPGA and tournament managers announced that they had been unable to find a replacement sponsor, and that the 2009 tournament would be cancelled.
