The gold medal went to Kerri Walsh and Misty May who had a perfect record in the tournament, losing not a single set.
The reigning champions from the 2000 Olympics, Natalie Cook and Kerri Ann Pottharst, both had new partners for Athens and coincidentally met at the last sixteen stage where Cook's team took the honours.
Adriana Behar and Shelda Bede repeated their 2000 Olympic result, taking silver.
The teams in each pool were ranked first through fourth based on the number of matches won, W. In the event of a two-way tie, the winning team in the head-to-head match finished ahead.
The top two teams from each pool and the four best third placed teams (based on: first, matches won; second (in the event of a tie), set ratio SF/SA; and third (if there is still a tie), points ratio PF/PA) progressed through to the round of sixteen (single elimination tournament).
