The Shanghai Masters (also known as Shanghai Rolex Masters for sponsorship reasons) is a professional men's tennis tournament played on outdoor hard courts, and held annually in early October at the Qizhong Forest Sports City Arena in the Minhang District of Shanghai, People's Republic of China. The Shanghai Masters is chronologically the eighth out of the nine ATP World Tour Masters 1000 tournaments on the Association of Tennis Professionals (ATP) World Tour season, and is the only one not played in Europe or North America.
All matches are played in outdoor conditions at the Qizhong Arena, after the venue held the Tennis Masters Cup indoors from 2005 to 2008. The surface is a hard court one, specifically DecoTurf.
The venue was originally built in 2004 and 2005 to host the Tennis Masters Cup, after the ATP awarded the tournament to Shanghai for a three-year contract (2005 - 2007), later extended to a fourth year. The site was conceived to become the largest tennis venue in Asia, with a 15,000-seats main stadium featuring a retractable roof of eight steel panels representing Shanghai's city flower, the magnolia. As of 2013, the Arena's Grand Stand Court 1 stands in fifth place in the list of tennis stadiums by capacity, alongside Beijing's National Tennis Stadium (built for the 2008 Summer Olympics) and Wimbledon's Centre Court.
In preparation of the first edition of the Shanghai Masters, the venue was expanded with several new stadiums and courts constructed by August 2009, including a Grand Stand Court 2, with a seating capacity of 5,000 spectactors, and a Grand Stand Court 3, with a seating capacity of 3,000 spectators.
