|Format||Team match play|
The Astor Trophy is a women's team golf tournament between teams of amateurs golfers from Great Britain and Ireland, Australia, Canada, New Zealand and South Africa. It has been played every four years since 1959. From its foundation until 2007 it was called the Commonwealth Trophy. South Africa did not compete from 1963 to 1991. While it was called the Commonwealth Trophy, Irish golfers were not eligible. The trophy was presented by Nancy Astor, Viscountess Astor.
Each team plays the other four teams. Two matches are played each day, the tournament lasting five days. Each match is contested over one day with foursomes in the morning and singles in the afternoon.
In 2019 there were four players in each team. Each match consisted of two foursomes and four singles. Previously there were five players in each team and each match consisted of two foursomes and five singles. The winner of the match receives 1 point while in a tied match each side receives ½ point. The cup is decided by the number of team matches won. In the event of a tie the order is decided by the number of individual matches won, including a half point for each halved match. If the team are still tied then the cup is tied.
