The twelve teams in the tournament were divided into two pools of six, with each team initially playing round-robin games within its respective pool. Following the completion of the round-robin, the top two teams from each pool advanced to the semifinals. All other teams played classification matches to determine the final tournament rankings. The two semi-final winners met for the gold medal match, while the semi-final losers played in the bronze medal match.
Each of the continental champions from five federations and the hosts China received an automatic berth. The European federation received two extra quotas, while Oceanian received one extra quota, based upon the FIH World Rankings at the completion of the 2006 World Cup. In addition to the three teams qualifying through the Olympic Qualifying Tournaments, the following twelve teams, shown with final pre-tournament rankings, competed in this tournament.[2][3]
^1 – China qualified both as host and continental champion, therefore that quota was given to the Asian federation allowing Japan to qualify directly to the 2008 Summer Olympics as the second-placed team at the 2006 Asian Games.
Fifteen umpires for the women's event were appointed by the FIH.[4] During each match, a video umpire was used to assist the on-field umpires in determining if a goal had been legally scored.[5]
As per statistical convention in field hockey, matches decided in extra time are counted as wins and losses, while matches decided by penalty shoot-outs are counted as draws.
